The notion of cylindricalgebra , invented by Alfred Tarski , arises naturally in the Algebraic logic algebraization of first order logic with First order logic Equality and its axioms equality . This is comparable to the role Boolean algebra structure Boolean algebra s play for propositional logic . Indeed, cylindric algebras are Boolean algebras equipped with additional cylindrification operations that model quantification and equality. They differ from polyadic algebra s in that the latter do not model equality.

In functional analysis , the Calkin algebra , named after J. W. Calkin, is the quotient space linear algebra quotient of B H , the ring algebra ring of bounded linear operator s on a separable space separable infinite dimensional Hilbert space H , by the ideal ring theory ideal K H of Compact operator on Hilbert space compact operator s. Since the compact operators is a in fact, the only maximal norm closed ideal in B H , the Calkin algebra is simple algebra simple . As a quotient of two C algebra s, the Calkin algebra is a C algebra itself. There is a short exact sequence math 0 rightarrow K H rightarrow B H rightarrow B H K H rightarrow 0 math which induces a six term cyclic exact sequence in K theory . Those operators in B H which are mapped to an invertible element of the Calkin algebra are called Fredholm operator s, and their index can be described both using K theory and directly. One can conclude, for instance, that the collection of unitary operators in the Calkin algebra are homotopy classes indexed by the integers Z . This is in contrast to B H , where the unitary operators are path connected. As a C algebra, the Calkin algebra is remarkable because it is not isomorphic to an algebra of operators on a separable Hilbert space instead, a larger Hilbert space has to be chosen the GNS theorem says that every C algebra is isomorphic to an algebra of operators on a Hilbert space for many other simple C algebras, there are explicit descriptions of such Hilbert spaces, but for the Calkin algebra, this is not the case . The same name is now used for the analogous construction for a Banach space . The Calkin algebra is the Corona algebra of the algebra of compact operators on a Hilbert space.

In mathematics , the Griess algebra is a commutative Algebra over a field Non associative algebras non associative algebra on a real number real vector space of dimension 196884 that has the Monster group M as its automorphism group . It is named after mathematician R. L. Griess , who constructed it in 1980 and subsequently used it in 1982 to construct M . The Monster fixes vectorwise a 1 space in this algebra and acts absolutely irreducibly on the 196883 dimensional orthogonal complement of this 1 space. The Monster preserves the standard inner product on the 196884 space. Griess s construction was later simplified by Jacques Tits and John H. Conway . The Griess algebra is the same as the degree 2 piece of the monster vertex algebra , and the Griess product is one of the vertex algebra products. References R. L.

In theoretical physics , a supersymmetry algebra or SUSY algebra is a symmetry algebra incorporating supersymmetry , a relation between boson s and fermion s. In a supersymmetry supersymmetric world, every boson would have a partner fermion of equal rest mass . Bosonic field s Commutative operation commute while fermionic field s anticommute. In order to relate the two kinds of fields in a single algebra, the introduction of a graded algebra Z sub 2 sub grading under which the even elements are bosonic and the odd elements are fermionic is required. Such an algebra is called a Lie superalgebra . On the other hand, the spin statistics theorem shows that bosons have integer spin, while fermions have half integer spin. Consequently, the odd elements in a supersymmetry algebra need to have half integer spin, in contrast to the tensor ial symmetries which are more traditional symmetries in physics. Just as one can have representations of a Lie algebra , one can also have representation of a Lie superalgebra representations of a Lie superalgebra . For each Lie algebra, there exists an associated Lie group which is connected space connected and simply connected . Unique up to isomorphism, this Lie group is canonically associated with the Lie algebra, and the representations of the algebra can be extended to create group representations. In the same way, representations of a Lie superalgebra can sometimes be extended into representations of a Lie supergroup .
