Pi-complemented algebras

For an ideal U of a nonassociative algebra A, the pi-closure of U is defined by overline{U} = Ann(Ann(U)), where Ann(.) denotes the annihilator relative to the algebra A. An algebra A is said to be pi-complemented if for every pi-closed ideal U of A there exists a pi-closed ideal V of A such that A is the direct sum of U and V. In this paper we shall develop a structure theory for pi-complemented algebras.
