THE CONTINUITY'' OF MULTIPLICATION ON THEOPERATOR ALGEBRA z(A,Y)(I)
算子代数∑(X,Y)的乘法连续性(Ⅰ)

In this paper, we discuss the continuity of multiplication on the operator algebra X(X,Y) which consists of all linear operators o'n a vector space X. The continuity ic f multiplication with respect to three locally convex topologies on I(X, Y)is solved.
