Quantum $U$ -channels on $S$ -spaces

Priyabrata Bag, Azad Rohilla, Harsh Trivedi

If the symmetry, (an operator $J$ satisfying $J = J^{*} = J^{- 1}$ ) which defines the Krein space, is replaced by a (not necessarily self-adjoint) unitary, then we have the notion of an $…

The order- $n$ minors of certain $(n + k) \times n$ matrices

Priyabrata Bag, Santanu Dey, Masaru Nagisa +1

We determine sufficient conditions for certain classes of $(n + k) \times n$ matrices $E$ to have all order- $n$ minors to be nonzero. For a special class of $(n + 1) \times n$ matrices…
