The aim of the present investigation is to establish the composition formulas for the pathway fractional integral operator connected with Hurwitz-Lerch zeta function and extended Wright-Bessel function. Some interesting special cases have also been discussed.

In this paper, we propose an extension of the classical Bessel function by means of our ℓ-hypergeometric function [2]. As the main results, the infinite order differential equation, the generating function relation, and contour integral representations including Schläfli's integral analogue are derived. With the aid of these, other results including some inequalities are also obtained. At the end, the graphs of these functions are plotted using the Maple software.

In this paper, we have studied f-biharmonic submanifolds in locally conformal almost cosymplectic space forms and have derived condition on second fundamental form for f-biharmonic submanifolds. Also, we have discussed its integral submanifolds in locally conformal almost cosymplectic space forms.

This paper presents a fundamental theorem of calculus, an integration by parts formula and a version of equiintegrability convergence theorem for the M_α-integral using the M_α-strong Lusin condition. In the convergence theorem, to be able to relax the condition of being point-wise convergent everywhere to point-wise convergent almost everywhere, the uniform M_α-strong Lusin condition was imposed.

In this paper an improved version of a fixed point theorem of the present author [3] in Banach algebras is obtained under the weaker conditions with a different method and using measure of non-compactness. The newly developed fixed point theorem is further-applied to certain nonlinear integral equations of mixed type for proving the existence theorems and stability of the solution in Banach algebras.

Let B be the open unit ball in the complex space $\mathbb{C}^n$. A holomorphic function $f:B{\rightarrow}C$ which satisfies sup{(1- ${\parallel}\;{\nabla}_zf\;{\parallel}\;{\mid}z{\in}B$} < $+{\infty}$ is called Bloch type function. In this paper, we will find some integral representation of Bloch type functions.

In the present paper we introduce a new subclass of analytic functions in the unit disc defined by convolution $(f_{\mu})^{(-1)}*f(z)$; where $$f_{\mu}=(1-{\mu})z_2F_1(a,b;c;z)+{\mu}z(z_2F_1(a,b;c;z))^{\prime}$$. Several interesting properties of the class and integral preserving properties of the subclasses are also considered.

본 논문은 이차하중을 받는 고온 구조물의 $C(t)$-적분 예측을 위한 탄성추종 계수를 결정하는 기법을 제시한다. 이차하중을 받는 구조물의 과도 크리프 상태의 크리프 균열 진전률은 $C(t)$를 이용하여 정량화할 수 있다. 이차하중을 받는 구조물에서 발생할 수 있는 탄성추종 현상은 응력 완화를 방해하므로, 탄성추종 현상이 증가하면 $C(t)$와 크리프 균열 진전률이 증가한다. Ainsworth 와 Dean 은 참조응력법에 기반하여 $C(t)$ 예측식을 제시하였는데, 이 식을 계산하기 위해서는 탄성추종 계수가 필요하다. 본 연구에서 고온 균열 구조물의 크리프에 의한 탄성추종 계수를 결정하는 방법을 제시하였다. 소성-크리프 유사성을 이용하여 탄소성 유한요소해석으로 크리프 탄성추종 계수를 결정할 수 있다. 유한요소해석을 이용하여 이 탄성추종 계수 결정법을 검증하였다.
