In this monograph we apply the idea of a TQFT to maps from manifolds to topological spaces. This leads us to a notion of a (''d'' + 1)-dimensional homotopy quantum field theory (HQFT) which may be described as a TQFT for closed oriented ''d''-dimensional manifolds and compact oriented (''d'' + 1)-dimensional cobordisms endowed with maps to a given space ''X''.

5. The relationship between two continuous functions where homotopy from one to the other is evident.

6. (ellipsis of) (gloss).

7. A theory associating a system of groups with each space.

8. A system of groups associated with a topological space.
