Abstract :
We shall state the following parametric extensions of Shannon inequality and its reverse one in Hilbert space operators. Let pset membership, variant[0,1] and also let {A1,A2,…,An} and {B1,B2,…,Bn} be two sequences of strictly positive operators on a Hilbert space H such that ∑j=1nAjmusical sharppBjless-than-or-equals, slantI. Thenimage∑j=1nSp+1(AjBj)greater-or-equal, slanted × loggreater-or-equal, slantedloggreater-or-equal, slanted∑j=1nSp(AjBj)greater-or-equal, slanted−loggreater-or-equal, slanted− × loggreater-or-equal, slanted∑j=1nSp−1(AjBj),where image for A>0, B>0 and any real number q and image for A>0, B>0 and any real number q.
