From discrete flow of Beckner to continuous flow of Janson in complex hypercontractivity [PDF]
We show how Beckner's montonicity result on Hamming cube easily implies the monotonicity of a flow introduced by Janson in Hausdorff--Young ...

Continuity and Discontinuity of Seminorms on Infinite-Dimensional Vector Spaces [PDF]
Let $S$ be a seminorm on an infinite-dimensional real or complex vector space $X$. Our purpose in this note is to study the continuity and discontinuity properties of $S$ with respect to certain norm-topologies on $X$.

Some inequalities for $(\alpha, \beta)$-normal operators in Hilbert spaces
An operator $T$ acting on a Hilbert space is called $(\alpha ,\beta)$-normal ($0\leq \alpha \leq 1\leq \beta $) if \begin{equation*} \alpha ^{2}T^{\ast }T\leq TT^{\ast}\leq \beta ^{2}T^{\ast}T.
