For compacta X and Y , let SC p (X ร— Y ) be the space of all separately continuous functions on the product X ร— Y with the topology of pointwise convergence. We prove that any compact subspace Z in SC p (X ร— Y ) is a Corson compactum in the case where X or Y is ccc (= has the Souslin property). We s

In this paper, we obtain some estimates for the ฮณ -diagonally and product ฮณ -diagonally dominant degree of the Schur complement of matrices. As application we present some bounds for the eigenvalues of Schur complement by the entries of the original matrix. Based on these results, we give a kind of
