چکیده

We shall show that the three variable cubic inequality t(a + b + c) + (t − 2t)(ab + bc + ca) ≥ (2t − 1)(ab + bc + ca) + (3t − 6t + 3t − 6t + 3)abc holds for non-negative a, b, c, and for any real number t. We also show some similar three variable cyclic quartic inequalities.

On the Cyclic Homogeneous Polynomial Inequalities of Degree Four of Three Nonnegative Real Variables

Let f (x,y,z) is a cyclic homogeneous polynomial of degree four of three nonnegative real variables satisfying the condition f (1,1,1) = 0 . We find necessary and sufficient condition to be true the inequality f (x,y,z) 0 , for this aim we introduce a characteristic polynomial Jf (t) and by its root t0 > 0 we formulate the condition.

Singular value inequalities for positive semidefinite matrices

In this note‎, ‎we obtain some singular values inequalities for positive semidefinite matrices by using block matrix technique‎. ‎Our results are similar to some inequalities shown by Bhatia and Kittaneh in [Linear Algebra Appl‎. ‎308 (2000) 203-211] and [Linear Algebra Appl‎. ‎428 (2008) 2177-2191]‎.

On the study of Hilbert-type inequalities with multi-parameters: a Survey

In this paper, we provide a short account of the study of Hilbert-typeinequalities during the past almost 100 years by introducing multi-parametersand using the method of weight coefficients. A basic theorem of Hilbert-typeinequalities with the homogeneous kernel of −−degree and parameters is proved.
