摘要：

Let G be a finite group and K a finite field of characteristic 2. Denote by t the 2-rank of the commutator factor group G/G ' and by s the number of isomorphism classes of self-dual simple KG-modules. Then the Witt group of equivariant quadratic forms WQ(K,G) is isomorphic to an elementary abelian 2-group of rank s+t.
