摘要

We continue our investigations on pointwise multipliers for Besov spaces of dominating mixed smoothness.This time we study the algebra property of the classes Sτp,qB(Rd) with respect to pointwise multiplication.In addition,if p ≤ q,we are able to describe the space of all pointwise multipliers for Sτp,qB(Rd).
