Abstract: | Let A, B, and X be bounded linear operators on a complex separable Hilbert space. It is shown that if A and B are self-adjoint with and for some real numbers a
1, a
2, b
1, and b
2, then for every unitarily invariant norm|||·|||,
. If, in addition, X is positive, then
. These norm inequalities generalize recent related inequalities due to Kittaneh, Bhatia-Kittaneh, and Wang-Du.
