On multilinear components of prime subvarieties in the variety Var(M 1,1)

Let M _1,1 be the matrix superalgebra over an infinite field of positive characteristic p ≠ 2. Multilinear identities of prime subvarieties in the variety Var M _1,1 are described. It is shown that the set of multilinear identities of any prime subvariety in the variety Var M _1,1 either coincides with the set of multilinear identities of the algebra M _1,1 or is generated by the identity x, y, z] = 0 or is generated by the identity x, y] = 0.
