Asymptotic Expansive and Hyperbolic Linear Operators

Priyabrata Bag, Pabitra Narayan Mandal, Pramod Kumar Das

We study the topological dynamical notion of asymptotic expansivity for linear operators. We also introduce two new notions, namely strong asymptotic expansivity and super asymptot…

Equivalence of Variants of Shadowing of Free Semigroup Actions

Pramod Kumar Das, Priyabrata Bag

We prove that for finitely generated free semigroup actions the average shadowing property, the weak asymptotic average shadowing property, the mean ergodic shadowing property, the…

Quantum -channels on -spaces

Priyabrata Bag, Azad Rohilla, Harsh Trivedi

If the symmetry, (an operator satisfying ) which defines the Krein space, is replaced by a (not necessarily self-adjoint) unitary, then we have the notion of an $…

The order- minors of certain matrices

Priyabrata Bag, Santanu Dey, Masaru Nagisa +1

We determine sufficient conditions for certain classes of matrices to have all order- minors to be nonzero. For a special class of matrices…

Comparing Geometric Discord and Negativity for Bipartite States

Priyabrata Bag, Santanu Dey, Hiroyuki Osaka

The geometric discord of a state is a measure of the quantumness of the state and the negativity is a measure of the entanglement of a state. It was pro…

A Subspace of Maximal Dimension with Bounded Schmidt Rank

Priyabrata Bag, Santanu Dey

We study Schmidt rank for a vector (i.e., a pure state) and Schmidt number for a mixed state which are entanglement measures. We show that if a subspace of a certain bipartite syst…

-Frobenius Negacyclic Codes

Priyabrata Bag, Santanu Dey

Let denote the finite field of order , where is an odd prime. We study certain quantum negacyclic codes over which we call -Frobenius negacy…
