Abstract: Cohomology groups H q(X,E) E^{pq}_2 = H^p(X, \pi_{-q} E ) \implies H^{p+q}(X, E) chunk78422660categorychunk --- ## Generalized sheaf cohomology [MathSciNet](http://www.ams.org/mathscinet/search/publications.html?pg4=AUCN&H^q(X,E) are defined, where XX is a topological space, and EE is sheaf on XX with values in Kan’s category of spectra. These groups generalize the ordinary cohomology groups of XX with coefficients in an abelian sheaf, as well as the generlized cohomology of XX in the usual sense. The groups are defined by means of the “homotopical algebra” of Quillen applied to suitable categories of sheaves. The study of the homotopy category of sheaves of spectra requires an abstract homotopy theory more general than Quillen’s, and this is developed in Part 1 of the paper. Finally, the basic cohomological properties are proved, including a spectral sequence (in generalized cohomology theory) which generalizes the Atiyah-Hirzebruch spectral sequence (in generalized cohomology theory) and the “locak to global” spectral sequence (in sheaf cohomology theory).
