 Stable model category

Stable model categories are a specific type of model category in which the homotopy theory is enriched with certain duality properties. They arise from the interplay between homotopy theory and stable homotopy theory, and they are particularly useful in contexts like derived categories and the study of spectra. A model category consists of: 1. **Objects**: These can be any kind of mathematical structure (like topological spaces, chain complexes, etc.).
