序言


This book is primarily concerned with the study of cohomology theories ofgeneral topological spaces with“general coefficient systems.’’Sheaves playseveral roles in this study.For example.they provide a suitable notion of“general coefl~cient systems.”Moreover.they furnish US with a commonmethod of defining various cohomology theories and of comparison betweendifferent cohomology theories.
The parts of the theory of sheaves covered here are those areas impor.tant to algebraic topology.Sheaf theory is also important in other fields ofmathematics,notably algebraic geometry,but that iS outside the scope ofthe present book.Thus a more descriptive title for this book might havebeen Algebraic Topology b-om the Point View ol Sheaf Theory.
Several innovations will be found in this book. Notably,the con.cept of the“gautness’’of a subspace ran adaptation of an analogous no.tion of Spanier to sheaf-theoretic cohomologyl iS introduced and exploitedthroughout the book.The fact that sheaf-theoretic cohomology satisfiesthe homotopy property is proved for general topological spaces.1 Also,relative cohomology iS introduced into sheaf theory.Concerning relativecohomology,it should be noted that sheaf-theoretic cohomology iS usuallyconsidered as a“single space”theory.This is not without reason.sincecohomology relative to a closed subspace can be obtained by taking coef.ficients in a certain type of sheaf,while that relative to an open subspace(or,more generally,to a taut subspace)can be obtained by taking coho-mology with respect to a special family of supports.However,even in thesecases.it iS sometimes of notational advantage to have a relative cohomologytheory.For example,in our treatment of characteristic classes in ChapterIV the use of relative cohomology enables US to develop the theory in fullgenerality and with relatively simple notation.Our definition of relativecohomology in sheaf theory is the first fully satisfactory one to be given.It is of interest to note that.unlike absolute cohomology,the relative CO-homology groups are not the derived functors of the relative cohomologygroup in degree zero(but they usually are SO in most cases of interest).
