Cauchy Dual Subnormality for Toral 2-Isometric Operator-Valued 2-Variable Weighted Shift

Soumyadip Dey

In this paper, we show that if $T = (T_{1}, T_{2})$ is an analytic left-inverse commuting pair of toral $2$ -isometries satisfying the joint kernel condition, then it is unitar…

von Neumann Inequality for a class of Doubly Contractive Weighted Shifts

Soumyadip Dey, Rajeev Gupta, Surjit Kumar

In this article, we investigate the ball version of von Neumann inequality for the class of doubly contractive $d$ -tuple of weighted shift. We show that if the weighted shift is ba…

Generating the liftable mapping class groups of regular cyclic covers

Soumya Dey, Neeraj K. Dhanwani, Harsh Patil +1

Let $Mod (S_{g})$ be the mapping class group of the closed orientable surface of genus $g \geq 1$ , and let $LMod_{p} (X)$ be the liftable mapping class group associat…
