Weak solutions for a coupled system of Pettis-Hadamard fractional differential equations

open access: yesAdvances in Difference Equations, 2017
In this paper, by applying the technique of measure of weak noncompactness and Mönch’s fixed point theorem, we investigate the existence of weak solutions under the Pettis integrability assumption for a coupled system of Hadamard fractional differential ...

Discrete integrable equations and special functions [PDF]

open access: yesUfimskii Matematicheskii Zhurnal, 2017
Summary: A generic scheme based on the matrix Riemann-Hilbert problem theory is proposed for constructing classical special functions satisfying difference equations. These functions comprise gamma- and zeta functions, as well as orthogonal polynomials with corresponding recurrence relations.

An Integral Equation Involving Legendre Functions [PDF]

open access: yesJournal of the Society for Industrial and Applied Mathematics, 1964
Rodrigues’s formula can be applied also to (1.1) and (1.3) but here the situation is slightly more involved in that the integrals with respect to σ^2 are of fractional order and their inversion requires the knowledge of differentiation and integration of fractional order.

Some Integral Equations Involving Hypergeometric Functions [PDF]

open access: yesProceedings of the Edinburgh Mathematical Society, 1967
SummaryAn integral equation of the first kind, with kernel involving a hypergeometric function, is discussed. Conditions sufficient for uniqueness of solutions are given, then conditions necessary for existence of solutions. Conditions sufficient for existence of solutions, only a little stricter than the necessary conditions, are given; and with them ...

On Monotonic Integrable Solutions for Quadratic Functional Integral Equations [PDF]

open access: yesMediterranean Journal of Mathematics, 2012
The object of this paper is to study the stability of a nonlinear Urysohn functional integral equation \[ x(t)= f_1(t, x(\Phi_1(t)))+ f_2(t, x(t)) \int^t_0 u(t,s,x(\Phi_2(s)))\,ds,\quad t\in L. \]

Equations containing locally Henstock-Kurzweil integrable functions [PDF]

open access: yesApplications of Mathematics, 2012
The authors consider a functional integral equation of Volterra type \[ u(t)=h(t,u)+{}^{K}\int _a^t g(s,u(s),u)\, d\,s, \quad t\in [a,b), \] where \(-\infty

On some bessel-function integral equations

open access: yesAnnali di Matematica Pura ed Applicata, 1976
Two propositions of Bremekamp in the field of integral equations are revisited. Their common base is shown to be an elegant reciprocal relation between a pair of integral equations of Volterra type.
