Stratification (mathematics)

Stratification in mathematics often refers to a method of organizing or classifying mathematical objects based on certain properties or characteristics. This concept can arise in various areas of mathematics, including: 1. **Topology**: In algebraic topology, stratification refers to a way to decompose a topological space into simpler pieces called strata, which can be more easily studied. Each stratum is a subspace that is a manifold, and the overall space is constructed from these strata.
