The Serre spectral sequence is a powerful computational tool in algebraic topology that arises in the study of fibrations, allowing one to compute the homology or cohomology of a space based on the homological properties of its base and fiber. This sequence organizes information about the relationships between different layers of a fibration, making it easier to analyze complex topological spaces. It highlights connections between algebraic structures and topological features, bridging various areas of mathematics.
