refimprove date February 2010 In computabilitytheory a numbering is the assignment of natural number s to a Set mathematics set of objects like rational number s, Graph mathematics graph s or words in some language . A numbering can be used to transfer the idea of computability and related concepts, which are strictly defined on the natural numbers using computable function s, to different objects. Important numberings are the G del numbering of the terms in first order predicate calculus and numberings of the set of computable functions which can be used to apply results of computabilitytheory on the set of computable functions itself. Definition A numbering of a set math S math is a partial function partial surjective function math nu subseteq mathbb N to S. math The value of math nu math at math i math if defined is often written math nu i math instead of the usual math nu i math . math nu math is called a total numbering if math nu math is a total function . If math S math is a set of natural numbers, then math nu math is required to be a partial recursive function . If math S math is a set of subsets of the natural numbers, then the set math langle i,j rangle j in nu i math using the Cantor pairing function is required to be recursively enumerable . Examples Given a G del numbering math varphi i math we can define a numbering of the recursively enumerable set s by math W i mathrm domain varphi i math Properties It is often more convenient to work with a total numbering than with a partial one. If the domain function domain of a partial numbering is recursively enumerable then there always exists an equivalent total numbering. Comparison of numberings Using computable function we can define a partial ordering on the set of all numberings. Given two numberings math ...

In computabilitytheory , the mortality problem is a decision problem which can be stated as follows Given a Turing machine , decide whether it halts when run on any configuration not necessarily a starting one In the statement above, the configuration is a pair q, w , where q is one of the machine s states not necessarily its initial state and w is an infinite sequence of symbols representing the initial content of the tape. Note that while we usually assume that in the starting configuration all but finitely many cells on the tape are blanks, in the mortality problem the tape can have arbitrary content, including infinitely many non blank symbols written on it. Philip K. Hooper proved in 1966 that the mortality problem is undecidable problem undecidable . However, it can be shown that the set of Turing machines which are mortal i.e. halt on every starting configuration is recursively enumerable .

File Computability in Europe logo.jpg thumb 150px right Association CiE logo Computability in Europe CiE is an international organization of mathematicians, logicians, computer scientists, philosophers, theoretical physicists and others interested in new developments in computability and in their underlying significance for the real world. CiE originated as a research network in 2003, and the Association Computability in Europe was formed in July 2008. Its first and current president is Professor S. Barry Cooper , a mathematician from Leeds . CiE is also a major international conference series. The first CiE conference was held in Amsterdam in June, 2005, subsequent meetings being in Swansea , Wales CiE 2006 , Siena , Italy CiE 2007 , Athens CiE 2008 , and Heidelberg , Germany CiE 2009 . CiE 2010 will be in Ponta Delgada Azores , Portugal and CiE 2011 in Sofia , Bulgaria . CiE 2012 in Cambridge , England will be part of the Alan Turing Year . CiE aims to widen understanding and appreciation of the importance of the concepts and techniques of computabilitytheory, and to support the development of a vibrant multi disciplinary community of researchers focused on computability related topics. CiE positions itself at the interface between applied and fundamental research, prioritising mathematical approaches to computational barriers.

Annals ...Merge Computabilitytheory date August 2011 Logics for computability are formulations of logic which capture some aspect of computability as a basic notion. This usually involves a mix of special logical connective s as well as semantics which explains how the logic is to be interpreted in a computational way. Probably the first formal treatment of logic for computability is the realizability interpretation by Stephen Kleene in 1945, who gave an interpretation of intuitionistic number theory in terms of Turing machine computations. His motivation was to make precise the Heyting Brouwer Kolmogorov BHK interpretation of intuitionism, according to which proofs of mathematical statements are to be viewed as constructive procedures. With the rise of many other kinds of logic, such as modal logic and linear logic , and novel semantic models, such as game semantics , logics for computability have been formulated in several contexts. Here we mention two. Modal logic for computability Kleene s original ... computability and logic. It was extended to full higher order intuitionistic logic by Martin ...

A circuit in computertheory is a theoretical structure simulating electrical and data paths, in which voltage and binary values enter at the beginning of the circuit, go through gates which do some computation and output an answer. An important special case of circuits is the boolean circuit . Circuits are defined in terms of the gates they contain and the values the gates can take. For example, binary circuits values are Boolean data type boolean values, and the gates can be binary function binary AND and OR gates and unary NOT gates. In integer circuit s, the values are set of integers and the gates are set union, intersection, complement, and the arithmetic operations and math times math Formal definition A circuit is composed of a set of values math M math , a set of gate labels math L math which are families of functions from math M i math to math M math , where math i math is a non negative integer with math i 0 math for constant gates , and a labelled graph labelled directed acyclic graph , the labels of which are elements of math L math , a gate math g math can label a node math n math of in degree math i math if and only if math g math is defined on math M i math . Notions The nodes of in degree 0 are called the input nodes, or the leaves. If there is an edge from math g math to math g math then math g math is called a child of math g math , we suppose there is an order on the vertices, so we can speak of the math k math th child of a vertex when math k math is less than the in degree of this vertex.

T theory is a branch of discrete mathematics dealing with analysis of tree graph theory tree s and discrete metric spaces . General history As per Andreas Dress , T theory originated from a question raised by Manfred Eigen , a recipient of the Nobel Prize in Chemistry , in the late seventies. He was trying to fit twenty distinct transfer RNA t RNA molecule s of the Escherichia coli E. Coli bacterium into a tree. One of the most important concepts of T theory is the tight span of a metric space. If X is a metric space, the tight span T X of X is, up to isomorphism, the unique minimal injective metric space that contains X . John Isbell was the first to discover the tight span in 1964, which he called the injective envelope . Dress independently constructed the same construct, which he called the tight span. Application areas Phylogenetic analysis, which is used to create phylogenetic tree s. Online algorithm s k server problem k server problem Recent developments Bernd Sturmfels , Professor of Mathematics and ComputerScience at University of California, Berkeley Berkeley , and Josephine Yu classified six point metrics using T theory.

Although a Diploma for historic reasons, it would be considered a conversion Masters course at other institutions. The Diploma was the world s first full year taught course in computerscience, starting in 1953. It attracted students with degrees in mathematics, science and engineering. At its peak, there were 50 students on the course. UK government EPSRC funding was withdrawn in 2001 and student numbers dropped dramatically.
