Inertia and other properties of the matrix $[β (i, j)]$

Priyanka Grover, Veer Singh Panwar

Let $π (A)$ , $ξ (A)$ and $ν (A)$ , respectively, denote the number of positive, zero and negative eigenvalues of the matrix $A$ . Then the triplet $(π (A), ξ (A), ν (A))$ is called the \em…

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…

Positivity of Hadamard powers of a few band matrices

Veer Singh Panwar, A. Satyanarayana Reddy

Let $P_{G} ([0, \infty))$ and $P_{G}^{^{'}} ([0, \infty))$ be the sets of positive semidefinite and positive definite matrices of order $n$ , respectively, with nonnegative e…

Positivity properties of some special matrices

Priyanka Grover, Veer Singh Panwar, A Satyanarayana Reddy

It is shown that for positive real numbers $0 < λ_{1} < \dots < λ_{n}$ , $[\frac{1}{β ( λ _{i} , λ _{j} )}]$ , where $β (\cdot, \cdot)$ denotes the beta function, is infinitely divisi…
