The concept of Bounded Boolean extension of an group is due to A.L.Foster[1]. He demonstrated that each element of a p-ring R with unity can be represented as a type of Boolean vector over the Boolean algebra of all the idempotent elements of R. Later Penning [4] and Zemmer [9] have simplified the proof of A. L. Foster concerning a basis consisting of non zero elements of the additive subgroup of R by

its unity element. Subrahmanyam [ 5 ] motivated by the concept of A.L.Foster has introduced the notion of abstract vector space over a Boolean algebra ( simply Boolean vector space).In fact Boolean vector space is a natural generalization of this idea of A.L.Foster. The contribution of Subrahmanyam’s work is in [ 5,6,7]. Later Raja Gopala rao [2] has generalized the concept of B-vector spaces to vector spaces over regular rings ( simply R-vector spaces) . He studied several properties of these spaces in [ 2,3] , generalizing the results of Subrahmanayam. Also Venkateswarlu [8] has introduced the concept of direct sums in R- vector spaces and has proved that ) (∑ n i iG )* is a basis for ) (∑ n i iV if V1…..Vn are vector spaces over the same regular ring R having bases G1* , ……Gn* respectively. In this paper we introduce the concept of strong linear homomorphism from an R- Vector space V into another R-Vector space W and give a necessary and sufficient condition of a linear homomorphism to be strongly linear homomorphism ( see theorem 2.5) .Also we prove that G* is a basis for V then T(G*) is a basis for T(V) where T : V → W is an isomorphism(see theorem 2.6)
