Abstract: Kawanaka obtained explicit formulas for the structure constants in the Hecke algebra $H\left( {G\left( q \right),B\left( q \right)} \right)$ of a finite Chevalley group $G\left( q \right)$ . This note contains a geometric interpretation of these formulas, involving decompositions of Bruhat cells, in connected reductive algebraic groups.
