Intersection cohomology
Armand Borel
Birkhäuser
<P>This book is a publication in Swiss Seminars, a subseries of Progress in Mathematics. It is an expanded version of the notes from a seminar on intersection cohomology theory, which met at the University of Bern, Switzerland, in the spring of 1983. </P>  <P>This volume supplies an introduction to the piecewise linear and sheaf-theoretic versions of that theory as developed by M. Goresky and R. MacPherson in <EM>Topology </EM>19 (1980), and in <EM>Inventiones Mathematicae</EM> 72 (1983). While some familiarity with algebraic topology and sheaf theory is assumed, the notes include a self-contained account of further material on constructibility, derived categories, Verdier duality, biduality, and on stratified spaces, which is used in the second paper but not found in standard texts.</P>  <P> </P>  <P>"The volume should be useful to someone interested in acquiring some basic knowledge about the field..." —Mathematical Reviews </P>
