U+2A33 "⨳" Smash Product Unicode Character
Unicode Version 17.0
⨳
U+2A33 "⨳" Smash Product is a mathematical symbol used primarily in algebraic topology and homotopy theory to denote the smash product of two pointed topological spaces. This operation combines two spaces by taking their Cartesian product and then collapsing the union of their base point subspaces to a single point, effectively creating a new pointed space that preserves the base point structure. It is a fundamental construction for defining concepts such as suspension and the wedge sum, and it plays a key role in the study of spectra and stable homotopy groups.
