  • Abstract
    In this paper, we establish further improvements  of the Young inequality and its reverse. Then, we assert operator versions corresponding them. Moreover, an application including positive linear mappings is given. For example, if $A,Bin {mathbb B}({mathscr H})$ are two invertible positive operators such that $0begin{align*} Phi ^{2} bigg(A nabla _{nu} B+ rMm left( A^{1}+A^{1} sharp_{mu} B^{1} 2 left(A^{1} sharp_{frac{mu}{2}} B^{1} right)right)\ qquad +left(frac{nu}{mu} right) Mm bigg(A^{1}nabla_{mu} B^{1} A^{1} sharp_{mu} B^{1}bigg)bigg) \ quad leq left( frac{K(h)}{ Kleft( sqrt{{h^{’}}^{mu}},2 right)^{r^{’}}} right) ^{2} Phi^{2} (A sharp_{nu} B),end{align*}where $r=min{nu,1nu}$, $K(h)=frac{(1+h)^{2}}{4h}$,  $h=frac{M}{m}$, $h^{’}=frac{M^{’}}{m^{’}}$ and $r^{’}=min{2r,12r}$. The results of this paper generalize the results of recent years.
