Idea

The Serre spectral sequence or Leray-Serre spectral sequence is a spectral sequence for computation of singular homology of topological spaces in a Serre-fiber sequence of topological spaces.

Given a homotopy fiber sequence

F E X \array{ F &\longrightarrow& E \\ && \downarrow \\ && X }

over a simply connected space XX, then the corresponding cohomology Serre spectral sequence looks like

E 2 p,q=H p(X,H q(F))H p+q(E). E_2^{p,q}= H^p(X, H^q(F)) \Rightarrow H^{p+q}(E) \,.

The generalization of this from ordinary cohomology to generalized (Eilenberg-Steenrod) cohomology is the Atiyah-Hirzebruch spectral sequence, see there for details.

There is also a generalization to equivariant cohomology: for cohomology with coefficients in a Mackey functor withRO(G)-grading for representation spheres S VS^V, then for EXE \to X an FF-fibration of topological G-spaces and for AA any GG-Mackey functor, the equivariant Serre spectral sequence looks like (Kronholm 10, theorem 3.1):

E 2 p,q=H p(X,H V+q(F,A))H V+p+q(E,A), E_2^{p,q} = H^p(X, H^{V+q}(F,A)) \,\Rightarrow\, H^{V+p+q}(E,A) \,,

where on the left in the E 2E_2-page we have ordinary cohomology with coefficients in the genuine equivariant cohomology groups of the fiber.
