In sequent calculus , the completeness of atomic initial sequents states that initial sequents math VAR A VAR VAR A VAR where math VAR A VAR is an arbitrary formula can be derived from only atomic initial sequents math VAR p VAR VAR p VAR where math VAR p VAR is an atomic formula . This theorem plays a role analogous to eta expansion in lambda calculus , and dual to cut elimination and beta reduction . Typically it can be established by induction on the structure of math VAR A VAR , much more easily than cut elimination. References Gaisi Takeuti. Proof theory .

Bar induction is a reasoning principle used in Intuitionism intuitionistic mathematics , introduced by L.E.J. Brouwer . It is useful in giving constructive versions of classical logic classical results. It is based on an inductive argument. The goal of the principle is to prove properties of infinite streams of natural numbers, called choice sequence s in intuitionistic terminology, by inductively reducing them to decidable properties of finite lists. Given two predicates R and S on finite lists of natural numbers, assume the following conditions hold R is decidable Every choice sequence has a finite prefix satisfying R this is expressed by saying that R is a bar Every list satisfying R also satisfies S If all extensions of a list by one element satisfy S, then that list also satisfies S. Then we can conclude that S holds for the empty list. References Stephen Cole Kleene S.C. Kleene , R.E.

From 1964 to 1966 Van Dalen taught logic and mathematics at Massachusetts Institute of Technology MIT , and later University of Oxford Oxford . From 1967 he was professor at the University of Utrecht .

Foreignchar Emile Jaques Dalcroze Image Emile Jaques Dalcroze.jpg thumb mile Jaques Dalcroze mile Jaques Dalcroze July 6, 1865 ndash July 1, 1950 , was a Swiss composer, musician and music educator who developed eurhythmics , a method of learning and experiencing music through movement. The influence of eurhythmics can be seen in the Orff Schulwerk pedagogy, common in public school music education throughout the United States. The Dalcroze Method involves teaching musical concepts through movement. A variety of movement analogues are used for musical concepts, to develop an integrated and natural feel for musical expression. Turning the body into a well tuned musical instrument, Dalcroze felt, was the best path to generating a solid, vibrant musical foundation. The Dalcroze Method consists of three equally important elements eurhythmics , solf ge , and improvisation . ref Mead, V. H. 1996 . More than Mere Movement Dalcroze Eurhythmics. Music Educators Journal, 82 4 , 38 41. ref Together, according to Dalcroze, they comprise the essential musicianship training of a complete musician. In an ideal approach, elements from each subject coalesce, resulting in an approach to teaching rooted in creativity and movement. Dalcroze began his career as a pedagogue at the Geneva Conservatory in 1892, where he taught harmony and solf ge . It was in his solf ge courses that he began testing many of his influential and revolutionary pedagogical ideas. Between 1903 and 1910, Dalcroze had begun giving public presentations of his method. ref Mead, p.39. ref In 1910, with the help of German industrialist Wolf Dohrn, Dalcroze founded a school at Hellerau , outside of Dresden , dedicated to the teaching of his method. In Hellerau were taught a lot of people, among them Serge Wolkonsky Prince Serge Wolkonsky , Griner Vera Vera Alvang Griner , Valeria Cratina, Jelle Troelstra son of Pieter Jelles Troelstra , Inga and Ragna Jacobi, Albert Jeanneret Le Corbusier Le Corbusier s brother , M ... more details

distinguish In mathematical logic and computer science the symbol math vdash math has taken the name turnstile because of its resemblance to a typical turnstile if viewed from above. It is also referred to as tee and is often read as yields , proves , satisfies or entails . The symbol was first used by Gottlob Frege in his 1879 book on logic, Begriffsschrift ref Gottlob Frege , Begriffsschrift Eine der arithmetischen nachgebildete Formelsprache des reinen Denkens. Halle, 1879. ref . In TeX , the turnstile symbol math vdash math is obtained from the command tt vdash tt . In Unicode , the turnstile symbol big unicode big is called right tack and is at code point U 22A2 ref http unicode.org charts PDF U2200.pdf Unicode standard ref . On a typewriter , a turnstile can be composed from a vertical bar and a dash . In LaTeX there is the http www.ctan.org tex archive macros latex contrib turnstile turnstile package , which issues this sign in many ways, and is capable of putting labels below or above it, in the correct places. The article http www.tug.org pracjourn 2007 3 buchsbaum A Tool for Logicians is a tutorial on using this package. Meaning The turnstile is a binary relation. It has several different meanings in different contexts In proof theory , the turnstile is used to denote provability. For example, if T is a formal theory and S is a particular sentence in the language of the theory then math T vdash S math means that S is provable from T ref A. S. Troelstra and H.
