Well-posedness of elliptic-parabolic differential problem with integral condition
Қарағанды университетінің хабаршысы. Математика сериясыIn this paper, we study a class of nonlocal boundary value problems for elliptic-parabolic equations subject to integral-type conditions. Such problems naturally emerge in various physical and engineering contexts, including diffusion processes in ...

Positive Solutions for Higher Order Nonlocal Fractional Differential Equation with Integral Boundary Conditions [PDF]
Journal of Function Spaces, 2018 In this paper, by using the spectral analysis of the relevant linear operator and Gelfand’s formula, some properties of the first eigenvalue of a fractional differential equation were obtained; combining fixed point index theorem, sufficient conditions for the existence of positive solutions are established.

Positive solutions of nonlocal fractional boundary value problem involving Riemann–Stieltjes integral condition [PDF]
Journal of Applied Mathematics and Computing, 2020 In this paper, we investigate the existence of positive solutions for a nonlocal fractional boundary value problem involving Caputo fractional derivative and nonlocal Riemann-Stieltjes integral boundary condition. By using the spectral analysis of the relevant linear operator and Gelfand's formula, we obtain an useful upper and lower bounds for the ...

Inverse nodal problem for Dirac operator with integral type nonlocal boundary conditions
Mathematical Methods in the Applied Sciences, 2022 In this paper, Dirac operator with some integral type nonlocal boundary conditions is studied. We show that the coefficients of the problem can be uniquely determined by a dense set of nodal points. Moreover, we give an algorithm for the reconstruction of some coefficients of the operator.
