I'm taking my first discrete math course. One aspect of functions has me stumped. We're asked to list the functions from a two-element set to a three-element set. And then list all the functions from ...

This is a java program that demonstrates many basic functions in discrete mathematics and set theory. The class FunctionsChapter3Style uses OrderedPair objects within its methods.

Presents propositional logic, combinatorics, methods of proof, mathematical systems, algebra of sets, matrix algebra, relations and functions, recursion and generating functions, applications to ...

In this paper we prove the following theorem: let G be a discrete amenable group with nontrivial almost-periodic compactification, and let F be a complex-valued function defined in [-1, 1]; then F ...

Abstract: This letter introduces a novel discrete-time control barrier function (DCBF) that stems directly from discrete-time set invariance theory. The proposed DCBF provides necessary and sufficient ...
