Bidiagonal decompositions and total positivity of some special matrices

Priyanka Grover, Veer Singh Panwar

The matrix $S = [1 + x_{i} y_{j}]_{i, j = 1}^{n}, 0 < x_{1} < \dots < x_{n}, 0 < y_{1} < \dots < y_{n}$ , has gained importance lately due to its role in powers preserving total nonnegativity. We give an ex…

Subdifferential set of the joint numerical radius of a tuple of matrices

Priyanka Grover, Sushil Singla

An expression for the subdifferential set of the joint numerical radius of a tuple of matrices is obtained. Its applications to the Birkhoff-James orthogonality in the space consis…
