A syntactical proof of the Marriage Lemma

نویسنده

  • Thierry Coquand
چکیده

We give a proof of the classical Marriage Lemma 4] using completeness of hyperresolution. This argument is purely syntactical, and extends directly to the innnite case. As an application we give a purely syntactical version of a proof that resolution is exponential on the pigeonhole principle.

Fuzzy Linear Programming and its Application for a Constructive Proof of a Fuzzy Version of Farkas Lemma

The main aim of this paper is to deal with a fuzzy version of Farkas lemma involving trapezoidal fuzzy numbers. In turns to that the fuzzy linear programming and duality theory on these problems can be used to provide a constructive proof for Farkas lemma. Keywords Farkas Lemma, Fuzzy Linear Programming, Duality, Ranking Functions.

عدد تناوبی گراف‌ها

In 2015, Alishahi and Hajiabolhassan introduced the altermatic number of graphs as a lower bound for the chromatic number of them. Their proof is based on the Tucker lemma, a combinatorial counterpart of the Borsuk-Ulam theorem, which is a well-known result in topological combinatorics. In this paper, we present a combinatorial proof for the Alishahi-Hajiabolhassan theorem.

Topics in Graph Theory

Abstract. This paper is an exposition of some classic results in graph theory and their applications. A proof of Tutte’s theorem is given, which is then used to derive Hall’s marriage theorem for bipartite graphs. Some compelling applications of Hall’s theorem are provided as well. In the final section we present a detailed proof of Menger’s theorem and demonstrate its power by deriving König’s...

Equalising Terms by Diierence Reduction Techniques

In the eld of inductive theorem proving syntactical diierences between the induction hypothesis and induction conclusion are used in order to guide the proof BvHS91, Hut90, Hut]. This method of guiding induction proofs is called rippling / coloring terms and there is considerable evidence of its success on practical examples. For equality reasoning we use these annotated terms to represent synt...
