Some intersection theorems for finite sets
Web3.2 Logic for Finite Sets We include, for completeness, an axiomatization for the logic of cardinality comparison for finite sets. For finite sets, one does not have to worry about constructing new models of set theory, or whether or not the axiom of choice is true. The key principle is the Finite Cancellation principle of Scott [Sco64]: WebFeb 1, 1997 · The Complete Intersection Theorem for Systems of Finite Sets. Authors: Rudolf Ahlswede.

WebIn this paper, let $ q $ be a power of a prime, we construct several classes of new projective three-weight or four-weight linear codes over $ \mathbb{F}_q $ from the defining sets construction, and determine their weight distributions by using additive character sums. Especially, these codes are suitable for applications in secret sharing schemes.
