On Galois projective group rings

Let A be a ring with 1, C the center of A and G′ an inner automorphism group of A induced by {Uα in ​A/α in a finite group G whose order is invertible}. Let AG′ be the fixed subring of A under the action of G′.If A is a Galcis extension of AG′ with Galois group G′ and C is the center of the subring...
