New trace norm inequalities for 2 x 2 blocks of diagonal matrices
Christopher King, Michael Nathanson
Several new trace norm inequalities are established for 2n x 2n block matrices, in the special case where the four n x n blocks are diagonal. Some of the inequalities are non-commu…

Inequality for p-norms of positive matrices
C. King
This paper derives an inequality relating the p-norm of a positive 2 x 2 block matrix to the p-norm of the 2 x 2 matrix obtained by replacing each block by its p-norm. The inequali…
