and its representations, which are fundamental to understanding elementary particle physics and quantum mechanical states.

Sternberg’s work on the "semidirect product" of groups (e.g., the Euclidean group) and his treatment of the Poincaré group as a low-energy approximation is now informing a new generation of (GFTs). Theorists are constructing GFTs based on "Sternberg–Lie algebras"—where the algebra has a non-trivial 3-cocycle, corresponding to a 3-group. sternberg group theory and physics new
