More inequalities on numerical radii of sectorial matrices
In this article, we refine some numerical radius inequalities of sectorial matrices recently obtained by Bedrani , Kittaneh and Sababheh. Among other results, it is shown that if $A_i\in\mathbb{M}_n(\mathbb{C})$ with $W(A_i)\subseteq S_{\alpha}$, $i=1,2\cdots,n$, and $a_1,\cdots,a_n$ are positive re...
