Spectral problems in boundary value problems constitute a fundamental area of applied mathematics and mathematical physics, where the focus lies on determining eigenvalues and corresponding ...

Boundary value problems and integro-differential equations lie at the heart of modern applied mathematics, providing robust frameworks to model phenomena across physics, engineering and beyond. These ...

This paper investigates the existence of solutions for nonlinear fractional differential equations with integral boundary conditions on an unbounded domain. An example illustrating how the theory can ...

The operator L is elliptic and of second order in a domain Ω in RN. We consider the following boundary value problem: Lu = f in Ω and Bu = 0 on ∂ Ω, where B= ad/dn + β(d/dn is the conormal derivative ...
