WebApr 11, 2024 · In this paper we prove a new combinatorial inequality from which yet another simple proof of the Kruskal--Katona theorem can be derived. The inequality can be used to obtain a characterization of the extremal families for this minimization problem, giving an answer to the question of Füredi and Griggs.

The Cardinality of Sumsets: Different Summands
WebThere are two approaches to cardinality: one which compares sets directly using bijections and injections, and another which uses cardinal numbers. The cardinality of a set is also called its size, when no confusion with other notions of size is possible. WebSo it's not right just to say that if two sets are infinite then their cardinalities are equal. But if there is a surjective function from A to B then by one of the definitions of cardinality we say A ≤ B . – Mark Oct 4, 2024 at 20:41 Add a comment 0 Because of [ G: K] = [ G: H] [ H: K] and [ H: K] ≥ 1 we have [ G: K] ≥ [ G: H]. WebApr 11, 2024 · The first model uses only polynomially many variables and inequalities, the second model needs exponentially many inequalities while the number of variables is still polynomial, and the third model requires exponentially many variables but only polynomially many inequalities. screeds neal\u0027s
