Some new semi-exponential operators

Some Remarks about Almost Semi-hyponormal Operators

We define the class of almost semi-hyponormal operators on a Hilbert space and provide some sufficient conditions in which such operators are almost normal, that is their self-commutator is in the trace-class. Mathematics Subject Classification: 47B20

Some New Characterization Results on Exponential and Related Distributions

Eigenvalue distribution of some fractal semi-elliptic differential operators

We consider differential operators of type Au(x) = u(x) + (−1)t1 ∂ 2t1u(x) ∂x1 1 + (−1)t2 ∂ 2t2u(x) ∂x2 2 , x = (x1, x2) ∈ R2, and Sierpinski carpets Γ ⊂ R2. The aim of the paper is to investigate spectral properties of the fractal differential operator A−1 ◦ trΓ acting in the anisotropic Sobolev space W (t1,t2) 2 (R 2) where trΓ is closely related to the trace operator trΓ .

Some new results on semi fully fuzzy linear programming problems

There are two interesting methods, in the literature, for solving fuzzy linear programming problems in which the elements of coefficient matrix of the constraints are represented by real numbers and rest of the parameters are represented by symmetric trapezoidal fuzzy numbers. The first method, named as fuzzy primal simplex method, assumes an initial primal basic feasible solution is at hand. T...

New univalence criteria for some integral operators

In this work we consider some integral operators for analytic functions in the open unit disk and we obtain new univalence criteria for these integral operators, using Mocanu’s and Şerb’s Lemma, Pascu’s Lemma. Mathematics Subject Classification (2010): 30C45.
