Two Estimators on the Hadamard Product and Fan Product of Matrix
LI Yanyan
Abstract：Using the Brauer ovaloid theorem of deformation ,we gave the upper bound of Hadamard prod-uct for nonnegative matrix and the lower bound of Fan product for M-matrix.These two estimators im-proved the results given by Wang Feng .
