1. Collecting Things Together: Sets
verfasst von : David Makinson
Erschienen in: Sets, Logic and Maths for Computing
Abstract
In this chapter we introduce the student to the world of sets. Actually, only a little bit of it, enough to get going. After giving a rough intuitive idea of what sets are, we present the basic relations between them: inclusion, identity, proper inclusion, and exclusion. We describe two common ways of identifying sets, and look closely at the empty set, basic Boolean operations, generalized meet and union, and powersets.
