Abstract :In this work the boundedness and compactness properties of upper triangular one-band block operator matrices in the innite direct sum of Hilbert spaces have been studied. We also obtain the necessary and sucient conditions when these operators belong to Schatten-von Neumann classes.Keywords : Direct sum of Hilbert spaces, Upper triangular one-band block operator matrix, Compact operator
