On L-rays of toeplitz matrices
(Vali-e-Asr university of Rafsanjan, 2023-05-01)A toeplitz matrix or diagonal-constant matrix is a matrix in which each descending diagonal from left to right is constant. A matrix R is called integral row stochastic, if each row has exactly a nonzero entry, +1, and ...

Inverse eigenvalues problem of distance matrices via unit lower triangular matrices
(Vali-e-Asr university of Rafsanjan, 2023-05-01)In this paper, for a given set of real numbers such as $\sigma$ with only one positive number and zero summation, we find a distance matrix in which the given set $\sigma$ is its spectrum.Finally, we solve special ...

$n$-weak amenability of a certain class of function spaces
(Vali-e-Asr university of Rafsanjan, 2023-05-01)Let $A$ be a non-zero normed vector space and let $\varphi$ be a non-zero element of $A^*$ such that $\Vert \varphi \Vert \leq 1$. Assume that $K=\overline{B_1^{(0)}}$ is the closed unit ball of $A$. According to the ...
