What was discovered
Spectral sequences are a tool of homological algebra for computing homology groups through successive approximations, introduced by Jean Leray as a generalization of exact sequences.
What it led to
- systematic computation in algebraic topology
- advances in algebraic geometry and homological algebra
- Leray's sheaf theory
- standard tools in modern topology
