Compositional representation of rational functions
نویسندگان
چکیده
The rational functions are shown to coincide with the compositions of endmarkings, morphisms and inverses of injective morphisms. To represent a rational function x we need one ednmarking \xm, two morphisms au <x3 and one inverse of an injective morphism <x2 and then Resumé. — On montre que les fonctions rationnelles coïncident avec les compositions de marquages \im est un marquage terminal, <xly ot3 ésu e. n ontre que les jonctions rationnelles coïncident r _ _ ._,. . u terminaux, morphismes et inverses de morphismes injectifs. Plus précisément, toute fonction rationnelle x se représente sous la forme T = (xma1 a^" 1 a3 où jx, sont des morphismes et a2 est un morphisme injectif

Compositional Analysis of Expected Delays in Networks of Probabilistic I/O Automata
Probabilistic I/O automata (PIOA) constitute a model for distributed or concurrent systems that incorporates a notion of probabilistic choice. The PIOA model provides a notion of composition, for constructing a PIOA for a composite system from a collection of PIOAs representing the components. We present a method for computing completion probability and expected completion time for PIOAs. Our m...

متن کاملThe best uniform polynomial approximation of two classes of rational functions
In this paper we obtain the explicit form of the best uniform polynomial approximations out of Pn of two classes of rational functions using properties of Chebyshev polynomials. In this way we present some new theorems and lemmas. Some examples will be given to support the results.
متن کاملQUASI-PERMUTATION REPRESENTATIONS OF SUZtTKI GROUP
By a quasi-permutation matrix we mean a square matrix over the complex field C with non-negative integral trace. Thus every permutation matrix over C is a quasipermutation matrix. For a given finite group G, let p(G) denote the minimal degree of a faithful permutation representation of G (or of a faithful representation of G by permutation matrices), let q(G) denote the minimal degree of a fai...
