Abstract

In this paper, we characterize the so called property Lo,o\textbf{L}_{o,o} as defined by Dantas and Rueda Zoca, for compact, weak-weak continuous bilinear maps. Motivated by this we weaken this property by defining the weak Lo,o\textbf{L}_{o,o} for bilinear maps. We provide equivalence of the weak Lo,o\textbf{L}_{o,o} property of (X^πY,R)(X\hat{\otimes}_{\pi}Y,\mathbb{R}) for linear functionals and that of (X,Y;R)(X,Y;\mathbb{R}) for bilinear forms under certain conditions on XX and YY. Moreover, we have also established that under certain preassigned conditions, if a bilnear map TT belongs to a class which satisfies the property Lo,o\textbf{L}_{o,o} (resp. the weak Lo,o\textbf{L}_{o,o}) for bilinear maps, then TT^* is a member of a class of operators which satisfy the property Lo,o\textbf{L}_{o,o} (resp. the weak Lo,o\textbf{L}_{o,o}) for operators.

We find a problem in Proposition 3.11. Also the preprint contains a lot of typos. Keeping all these in mind we have decided to withdraw this preprint
