Cosheaves and Čech Homology
In this short chapter we study the notion of cosheaves on general topological spaces and we go into it a bit deeper than was done in Chapter V. Our main purpose, in this chapter, is to obtain isomorphism criteria connecting various homology theories. With the minor exceptions of some definitions, and excepting the sections (10 and 11) concerning Borel-Moore homology, this chapter does not depend on Chapter V.
