Rademacher-type formula and higher order TurÃ¡n inequalities for $ℓ$ -regular overpartitions

Priyanka Dey, Ajit Singh, Gurinder Singh

For $ℓ \geq 2$ , let $A_{ℓ} (n)$ count the number of overpartitions of $n$ with no parts divisible by $ℓ$ . In this article, we employ the circle method to derive a R…

Products of Idempotents in Banach Algebras of Operators

Surender K. Jain, AndrÃ© Leroy, Ajit Iqbal Singh

Let $X$ be a Banach space and $A$ be the Banach algebra $B (X)$ of bounded (i.e. continuous) linear transformations (to be called operators) on $X$ to itself. Let $\mathcal…

Useful variants and perturbations of completely entangled subspaces and spans of unextendible product bases

Ritabrata Sengupta, Ajit Iqbal Singh

Finite dimensional entanglement for pure states has been used extensively in quantum information theory. Depending on the tensor product structure, even set of separable states can…
