What was discovered
A theorem of algebraic topology relating the homology of two topological spaces to the homology of their product space, via a formula decomposing the product's homology groups from those of the factors; proved by Hermann Künneth.
What it led to
- Fundamental tool for computing the homology of product spaces
- Widely used in algebraic topology and homological algebra
- Extended to Künneth spectral sequences in generalized cohomology theories
