We derive the Levinson type generalization of the Jensen and the converse Jensen inequality for real Stieltjes measure, not necessarily positive. As a consequence, also the Levinson type generalization of the Hermite-Hadamard inequality is obtained. Similarly, we derive the Levinson type generalization of Giaccardi's inequality. The obtained results are then applied for establishing new mean-va...

Several new trace norm inequalities are established for 2n × 2n block matrices, in the special case where the four n × n blocks are diagonal. Some of the inequalities are non-commutative analogs of Hanner's inequality , others describe the behavior of the trace norm under reordering of diagonal entries of the blocks.
