The Algebra of Sets
If { Ai } and { Bj } are two classes of sets such that { Ai } is subset of { Bj },
show that Ui Ai is subset Uj Bj and ∩j Bj is subset of ∩i Ai.
This is a topology proof regarding sets and subsets.

- Topologies : Open Sets - • Let X:={a,b,c} be a set of three elements. A certain topology of X contains (among others) the sets {a}, {b}, and {c}. List all open sets in the topology T. • Let X':={a,b,c,d,e} be a set of five e ...
- Sets and Functions : Subset Relations - Let U be the set { 1, 2 }. There are four subsets . List them. If A and B are arbitrary subsets of U, there are 16 possible relations of the form "A is subset of B". Count the number of true ones. ...
