A LIOUVILLE TYPE THEOREM FOR HARMONIC MORPHISMS

open access: yesJournal of the Korean Mathematical Society, 2007
Let M be a complete Riemannian manifold and let N be a Riemannian manifold of nonpositive scalar curvature. Let μ0 be the least eigenvalue of the Laplacian acting on L2-functions on M . We show that if RicM ≥ −μ0 at all x ∈ M and either RicM > −μ0 at some point x0 or Vol(M) is infinite, then every harmonic morphism φ : M → N of finite energy is ...

Exponential stability of solutions of nonlinear fractionally perturbed ordinary differential equations

open access: yesElectronic Journal of Differential Equations, 2017
The main aim of this paper is to prove a theorem on the exponential stability of the zero solution of a class of integro-differential equations, whose right-hand sides involve the Riemann-Liouville fractional integrals of different orders and we ...

A Note on Fractional Equations of Volterra Type with Nonlocal Boundary Condition

open access: yesAbstract and Applied Analysis, 2013
We deal with nonlocal boundary value problems of fractional equations of Volterra type involving Riemann-Liouville derivative. Firstly, by defining a weighted norm and using the Banach fixed point theorem, we show the existence and uniqueness of ...
