This article is an creation to topology and homotopy. subject matters are built-in right into a coherent complete and constructed slowly so scholars usually are not crushed. the 1st half the textual content treats the topology of whole metric areas, together with their hyperspaces of sequentially compact subspaces. the second one half the textual content develops the homotopy classification. there are lots of examples and over 900 workouts, representing quite a lot of hassle. This publication may be of curiosity to undergraduates and researchers in arithmetic.
