Some refinements of numerical radius inequalities
UDC 517.5 In this paper, we give some refinements for the second inequality in $\dfrac{1}{2}\|A\| \leq w(A) \leq \|A\|,$  where $A\in B(H).$  In particular, if $A$ is hyponormal by refining the Young inequality with the Kantorovich constant $K(\cdot, \cdot),...
