A Simple Proof for the TuringCompleteness
, 2004
"... The World Wide Web Consortium recommends both XSLT and XQuery as query languages for XML documents. XSLT, originally designed to transform XML into XSLFO, is nowadays a fully grown XML query language that is mostly suited for use by machines. XQuery on the other hand was particularly designed to be ..."

to be easily used by humans. Both languages are known to be Turingcomplete. We provide here a very simple proof of Turingcompleteness of XSLT and XQuery by codingrecursive functions thereby showing that Turingcompleteness is a consequence of a few basic and fundamental features of both languages. A Simple
A Transformation System for Developing Recursive Programs
, 1977
"... A system of rules for transforming programs is described, with the programs in the form of recursion equations An initially very simple, lucid. and hopefully correct program IS transformed into a more efficient one by altering the recursion structure Illustrative examples of program transformations ..."

Department, Stanford, CA 94305, (email: jmc@cs.stanford.edu), (URL: http://wwwformal.stanford.edu/jmc/ ) by starting with the class of expressions called Sexpressions and the functions called Sfunctions. In this article, we first describe a formalism for defining functions recursively. We believe
PDDL2.1: An Extension to PDDL for Expressing Temporal Planning Domains
, 2003
"... In recent years research in the planning community has moved increasingly towards application of planners to realistic problems involving both time and many types of resources. For example, interest in planning demonstrated by the space research community has inspired work in observation scheduling, ..."

the development of a modelling language capable of expressing temporal and numeric properties of planning domains. In this paper we describe the language, PDDL2.1, that was used in the competition. We describe the syntax of the language, its formal semantics and the validation of concurrent plans. We observe

TuringCompleteness of Polymorphic Stream Equation Systems
"... Polymorphic stream functions operate on the structure of streams, infinite sequences of elements, without inspection of the contained data, having to work on all streams over all signatures uniformly. A natural, yet restrictive class of polymorphic stream functions comprises those definable by a sys ..."
Abstract
 Add to MetaCart
this holds true even for unary equations free of mutual recursion, yielding an elegant model of Turingcompleteness in a severely restricted environment and allowing us to recover previous complexity results in a much more restricted setting.
GromovWitten classes, quantum cohomology, and enumerative geometry
 Commun. Math. Phys
, 1994
"... The paper is devoted to the mathematical aspects of topological quantum field theory and its applications to enumerative problems of algebraic geometry. In particular, it contains an axiomatic treatment of Gromov–Witten classes, and a discussion of their properties for Fano varieties. Cohomological ..."

PseudoRandom Generation from OneWay Functions
