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 ...

Read Levin's chapter on functions. Go over the exercises at the end. Note that Levin skips over the more general notion of relation -- he comes to it in a later stage, though. We will talk about ...

Course Description: A course designed to prepare math, computer science, and engineering majors for future coursework by introducing formal mathematical concepts and techniques that are fundamental ...

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 ...
