چکیده

The Gale–Nikaido–Debreu lemma plays an important role in establishing the existence of competitive equilibrium. In this paper, we use Sperner’s and basic elements topology to prove lemma.

A simple proof of Zariski's Lemma

‎Our aim in this very short note is to show that the proof of the‎ ‎following well-known fundamental lemma of Zariski follows from an‎ ‎argument similar to the proof of the fact that the rational field‎ ‎$mathbb{Q}$ is not a finitely generated $mathbb{Z}$-algebra.

Proof of Lemma

Let E be a measurable set in R such that 0 < |E| < ∞. We will say that E tiles R by translations if there is a discrete set T ⊂ R such that, up to sets of measure 0, the sets E + t : t ∈ T are mutually disjoint and ⋃ t∈T (E + t) = R . We call any such T a translation set for E, and write that E + T = R is a tiling. It is known [19], [18] that if a convex set E tiles R by translations, it must b...

A simple proof of the Isolation Lemma

We give a new simple proof for the Isolation Lemma, with slightly better parameters, that also gives non-trivial results even when the weight domain m is smaller than the number of variables n. 1 The lemma and its proof Let n,m be two natural numbers, F ⊆ P([n]), where [n] = {1, . . . , n} and P([n]) is the set of all subsets of [n]. A weight function is a function w : [n] → [m]. Given a weight...
