Some applications of linear algebraic methods in combinatorics
Maryam Khosravi, Ebadollah S. Mahmoodian
In this note, we intend to produce all latin squares from one of them using suitable move which is defined by small trades and do the similar work on 4-cycle systems. These problem…
Some Hadamard product inequalities for accretive matrices
A. Sheikhhosseini, S. Malekinejad, M. Khosravi
In this paper, we obtain some new matrix inequalities involving Hadamard product. Also some Hadamard product inequalities for accretive matrices involving the matrix means, positiv…
Operator mean inequalities for sector matrices
M. Khosravi, A. Sheikhhosseini, S. Malekinejad
In this note, some inequalities involving operator means of sectorial matrices are proved which are generalizations and refinements of previous known results. Among them, let a…
