Strictly sub row Hadamard majorization [PDF]

open access: yesJournal of Mahani Mathematical Research, 2022
‎Let $\textbf{M}_{m,n}$ be the set of all $m$-by-$n$ real matrices‎. ‎A matrix $R$ in $\textbf{M}_{m,n}$ with nonnegative entries is called strictly sub row stochastic if the sum of entries on every row of $R$ is less than 1‎. ‎For $A,B\in\textbf{M}_{m,n}

On the generalized Hadamard product and the Jordan-Hadamard product [PDF]

open access: yesBulletin of the Australian Mathematical Society, 1980
The generalized Hadamard product S * T and the Jordan-Hadamard product S ∘ T of two operator-matrices S and T are introduced. They coincide with the usual Hadamard product of two complex matrices when the underlying Hilbert spaces are one-dimensional. Some inequalities which hold true for the usual Hadamard product of positive definite complex matrices

Quantum Inequalities of Hermite–Hadamard Type for r-Convex Functions

open access: yesJournal of Mathematics, 2021
In this present study, we first establish Hermite–Hadamard type inequalities for r-convex functions via qκ2-definite integrals. Then, we prove some quantum inequalities of Hermite–Hadamard type for product of two r-convex functions.
