Reconstruction of the Volterra-type integro-differential operator from nodal points

open access: yesBoundary Value Problems, 2018
In this work, the Sturm–Liouville problem perturbated by a Volterra-type integro-differential operator is studied. We give a uniqueness theorem and an algorithm to reconstruct the potential of the problem from nodal points (zeros of eigenfunctions).

Fractional Noether's Theorem with Classical and Riemann-Liouville Derivatives

open access: yes, 2012
We prove a Noether type symmetry theorem to fractional problems of the calculus of variations with classical and Riemann-Liouville derivatives. As result, we obtain constants of motion (in the classical sense) that are valid along the mixed classical ...

Uncertain fractional forward difference equations for Riemann–Liouville type

open access: yesAdvances in Difference Equations, 2019
To model complex systems with discrete-time features and memory effects in the uncertain environment, a definition of an uncertain fractional forward difference equation with Riemann–Liouville-like forward difference is introduced.

A Liouville theorem for superlinear heat equations on Riemannian manifolds

open access: yes, 2019
We study the triviality of the solutions of weighted superlinear heat equations on Riemannian manifolds with nonnegative Ricci tensor. We prove a Liouville--type theorem for solutions bounded from below with nonnegative initial data, under an integral ...

Nonexistence of positive solutions for the weighted higher-order elliptic system with Navier boundary condition

open access: yesBoundary Value Problems
We establish a Liouville-type theorem for a weighted higher-order elliptic system in a wider exponent region described via a critical curve. We first establish a Liouville-type theorem to the involved integral system and then prove the equivalence ...

Liouville-Type Theorem for Nonlinear Elliptic Equations Involving Generalized Greiner Operator

open access: yesMathematics, 2022
In this paper, we study the Liouville-type behaviors of the generalized Greiner operators with nonlinear boundary value conditions. We use the technique based upon the method of moving planes.
