Set Topology (Dover Books on Mathematics)

Excellent, well-written introductory text begins with the algebra of subsets and of rings and fields of sets. Placing the algebra of partial order within the context of topologic situations, it covers complementation and ideal theory in the distributive lattice, closure function, neighborhood topology, open and closed sets, topological maps, the derived set in T1-space and the topological product, and convergence in metrical space and convergence topology. Numerous exercises. 1960 edition. Prefaces. Index of Proper Names.
