Operator Inequalities and Several Characterizations of the $λ$ -Mean Transform

Bikram Das, Goutam Biswas, Chandal Nahak

We broaden Buzano-type inequalities to provide novel numerical radius bounds for operators of the type $A X B$ , thereby generalizing the results obtained by Sababheh et al. For the $…

New perspectives on operator radius bounds in $A -$ weighted frameworks

Bikram Das, Chandal Nahak

By employing the Moore $-$ Penrose inverse of a bounded linear operator, we derive several bounds for the numerical radius and operator norms of the sum of operators in semi $-$ Hilber…

Coloring discrete pseudomanifolds

Biplab Basak, Vanny Doem, Chandal Nahak

This paper presents three main results on coloring discrete $d$ -pseudomanifolds: $(1)$ the general chromatic bounds $d + 1 \leq X (K) \leq 2 d + 2$ for any $d$ -pseudomanifold $K$ ; $(2)$ …

Rational stable homotopy type of equivariant projective spaces and Grassmannians

Samik Basu, Vanny Doem, Chandal Nahak

We prove explicit rational stable splittings of equivariant complex projective spaces $C P (V)$ and Grassmannians $G r_{n} (V)$ , for complex representations $V$ . When $V$ is a s…
