• Brauer-Clifford group
• Equivariant Brauer group
• G-algebras

The notion of G-algebra equivalence for a group G is generalized from the setting of G-algebras over fields to G-algebras over commutative rings. This leads to a formulation of Turull's Brauer-Clifford group for separable G-algebras over commutative rings, and to connections with Frohlich and Wall's equivariant Brauer group.
