A three-point boundary value problem with an integral condition for a third-order partial differential equation

Abstract and Applied Analysis, 2005
We prove the existence and uniqueness of a strong solution for a linear third-order equation with integral boundary conditions. The proof uses energy inequalities and the density of the range of the operator generated.

On a Certain Subclass of Meromorphic Functions Defined by a New Linear Differential Operator

Journal of Mathematical and Fundamental Sciences, 2017
In this article, a new linear differential operator I^k (L_s^a (a_l,b_m )f(z)) is defined by using the Hadamard product of the q-hypergeometric function and a function related to the Hurwitz-Lerch zeta function. By using this linear differential operator,

An Operator Extension of Čebyšev Inequality

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017
Some operator inequalities for synchronous functions that are related to the čebyšev inequality are given. Among other inequalities for synchronous functions it is shown that ∥ø(f(A)g(A)) - ø(f(A))ø(g(A))∥ ≤ max{║ø(f2(A)) - ø2(f(A))║, ║ø)G2(A)) - ø2(g(A))
