In mathematical logic Frege s propositionalcalculus was the first axiomatization of propositionalcalculus . It was invented by Gottlob Frege , who also invented predicate calculus , in 1879 as part of his second order predicate calculus although Charles Sanders Peirce Charles Peirce was the first to use the term second order and developed his own version of the predicate calculus independently of Frege . It makes use of just two logical operators implication and negation, and it is constituted by six axiom s and one inference rule modus ponens . u Axioms u br THEN 1 A B A br THEN 2 A B C A B A C br THEN 3 A B C B A C br FRG 1 A B B A br FRG 2 A A br FRG 3 A A br u Inference Rule u br MP P, P Q Q br Frege s propositionalcalculus is equivalent to any other classical propositionalcalculus, such as the standard PC with 11 axioms. Frege s PC and standard PC share two common axioms THEN 1 and THEN 2. Notice that axioms THEN 1 through THEN 3 only make use of and define the implication operator, whereas axioms FRG 1 through FRG 3 define the negation operator. The following theorems will aim to find the remaining nine axioms of standard PC within the theorem space of Frege s PC, showing that the theory of standard PC is contained within the theory of Frege s PC. A theory, also called here, for figurative purposes, a theorem space , is a set of theorems which are a subset of a universal set of well formed formula s. The theorems are linked to each other in a directed manner by inference rule s, forming a sort of dendritic network. At the roots of the theorem space are found the axioms, which generate the theorem space much like a generating set generates a group.

In mathematical logic , a propositional variable also called a sentential variable or sentential letter is a Variable mathematics variable which can either be true or false . Propositional variables are the basic building blocks of propositional formula s, used in propositionallogic and higher logics. Formulas in logic are typically built up recursively from some propositional variables, some number of logical connective s, and some logical quantifier s. Propositional variables are the atomic formula s of propositionallogic. For example, in a given propositionallogic, we might define a formula as follows Every propositional variable is a formula. Given a formula X the negation X is a formula. Given two formulas X and Y , and a binary connective b such as the logical conjunction , then X b Y is a formula. Note the parentheses. In this way, all of the formulas of propositionallogic are built up from propositional variables as a basic unit. Propositional variables are represented as nullary Predicate mathematical logic predicates in first order logic .

A propositional function in logic , is a statement expressed in a way that would assume the value of truth true or contradiction false , except that within the statement is a Variable mathematics variable x that is not defined or specified, which leaves the statement undetermined. Of course, x could also consist of several variables. As a Function mathematics mathematical function , A x or A x1 , x2 , , xn , the propositional function is abstracted from predicate mathematical logic predicates or propositional forms. As an example, let s imagine the predicate, x is hot . The substitution of any entity for x will produce a specific proposition that can be described as either true or false, even though x is hot on its own has no value as either a true or false statement. However, when you assign x a value, such as lava , the function then has the value true while if you assign x a value like ice , the function then has the value false . Propositional functions are useful in set theory for the formation of set mathematics sets . For example, in 1903 Bertrand Russell wrote in The Principles of Mathematics page 106 ...it has become necessary to take propositional function as a primitive notion . Later Russell examined the problem of whether propositional functions were predicative or not, and he proposed two theories to try to get at this question the zig zag theory and the ramified theory of types. ref name Tiles Tiles, Mary The philosophy of set theory an historical introduction to Cantor s paradise . 2004.

A propositional attitude is a relational mental state connecting a person to a proposition . They are often assumed to be the simplest components of thought and can express meanings or content that can be true or false. In being a type of attitude psychology attitude they imply that a person can have different mental postures towards a proposition, for example, belief believing , desiring, or hope hoping , and thus they imply intentionality . Linguistically, they are denoted by an embedded that clause, for example, Sally believed that she had won . Propositional attitudes have direction of fit directions of fit some are meant to reflect the world, others to influence it.

In computer science , Api calculus was introduced in 2002 as an extension of pi calculus to address some of the limitations of pi calculus for modeling intelligent agents ref http www.cs.siu.edu rahimi rahimi ch7.pdf Rahimi 2002 Shahram Rahimi, Maria Cobb, Dia Ali, Fred Petry, A Modeling Tool for Intelligent Agent Based Systems Api Calculus, Soft Computing Agents A New Perspective for Dynamic Systems, the International Series Frontiers in Artificial Intelligence and Application by IOS Press, pp. 165 186, 2002. ref . More specifically, it addresses knowledge representation , organizational grouping and migration of agents among groups. Moreover, it has the potential for modeling the security aspects of Agent based model agent based systems . Api calculus introduces three new concepts over ordinary pi calculus and its extensions, the higher order and polyadic pi calculi. To represent knowledge inherent in an autonomous agent, the concept of a knowledge unit is introduced. A knowledge unit is an intelligence entity that can perform inference. Agents have the capability to add drop facts i.e. Predicate logic predicate s or Propositionalcalculus propositions to from a knowledge unit and also modify its structure by adding new rules or eliminating existing ones. Each mobile agent is capable of carrying one or more knowledge units and sending and receiving them to from other agents. However, the concept of knowledge unit only provides an abstraction level with no resources for intelligence modeling. Moreover, api calculus introduces milieu , a new level of abstraction that is in between single mobile agents and the system as a whole. And lastly, Api calculus introduces the notion of term . A term consists of a name, a rule fact used to create or modify knowledge units , or a function, where a name can be a channel or a variable.In the standard pi calculus, names are the only terms.

Unreferenced date January 2009 In mathematical logic , a proof calculus corresponds to a family of formal system s that use a common style of formal inference for its inference rules . The specific inference rules of a member of such a family characterize the theory mathematical logic theory of a logic. Usually a given proof calculus encompasses more than a single particular formal system, since many proof calculi are under determining and can be used for radically different logics. For example, a paradigmatic case is the sequent calculus, which can be used to express the consequence relation s of both intuitionistic logic and relevance logic . Thus, loosely speaking, a proof calculus is a template or design pattern , characterized by a certain style of formal inference, that may be specialized to produce specific formal systems, namely by specifying the actual inference rules for such a system. There is no consensus among logicians on how best to define the term. Examples of proof calculi The most widely known proof calculi are those classical calculi that are still in widespread use The class of Hilbert system s, of which the most famous example is the 1928 Hilbert Ackermann system of first order logic Gerhard Gentzen s calculus of natural deduction , which is the first formalism ... relating logic to functional programming Gentzen s sequent calculus , which is the most studied formalism ... proposed calculi with deep inference , for instance display logic , hypersequents , the calculus of structures , and bunched implication .

In mathematics , a functional calculus is a theory allowing one to apply mathematical function s to mathematical operator s. It is now a branch more accurately, several related areas of the field of functional analysis , connected with spectral theory . Historically, the term was also used synonymously with calculus of variations this usage is obsolete, but see functional derivative . Sometimes it is used in relation to types of functional equation , or in logic for systems of predicate calculus . If f is a function, say a numerical function of a real number , and M is an operator, there is no particular reason why the expression f M should make sense. If it does, then we are no longer using f on its original function domain . In the tradition of operational calculus , algebraic expressions in operators are handled irrespective of their meaning. This passes nearly unnoticed if we talk about squaring a matrix , though, which is the case of f x x sup 2 sup and M an n × n matrix mathematics matrix . The idea of a functional calculus is to create a principled approach to this kind of overloading of the notation. The most immediate case is to apply polynomial function s to a square matrix , extending what has just been discussed. In the finite dimensional case, the polynomial functional calculus yields quite a bit of information about the operator. For example, consider the family of polynomials which annihilates an operator T . This family is an ideal ring theory ideal in the ring ... calculus is not as informative in the infinite dimensional case. Consider the unilateral shift with the polynomials calculus the ideal defined above is now trivial. Thus one is interested in functional ... be.
