Rearrangements and Leibniz-type rules of mean oscillations
Zoltan Leka
We shall prove a rearrangement inequality in probability measure spaces in order to obtain sharp Leibniz-type rules of mean oscillations in Lp-spaces and rearrangement invariant Ba…

Some inequalities for central moments of matrices
Zoltan Leka
In this paper we shall study noncommutative central moment inequalities with a main focus on whether the commutative bounds are tight in the noncommutative case, or not. We prove t…
