Nonexistence of mean curvature flow solitons with polynomial volume growth immersed in certain semi-Riemannian warped products

Advances in Nonlinear Analysis
Our purpose is to establish nonexistence results concerning complete noncompact mean curvature flow solitons with polynomial volume growth immersed in certain semi-Riemannian warped products, under mild constraints on the warping and soliton functions ...

Harmonic-hyperbolic geometric flow

Electronic Journal of Differential Equations, 2017
In this article we study a coupled system for hyperbolic geometric flow on a closed manifold M, with a harmonic flow map from M to some closed target manifold N. Then we show that this flow has a unique solution for a short-time.

Instability of elliptic equations on compact Riemannian manifolds with non-negative Ricci curvature

Electronic Journal of Differential Equations, 2010
We prove the nonexistence of nonconstant local minimizers for a class of functionals, which typically appear in scalar two-phase field models, over smooth N-dimensional Riemannian manifolds without boundary and non-negative Ricci curvature ...

On a class of Riemannian manifolds with harmonic Weyl conformal curvature tensor

Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2004
The paper deals with the local structure of those $n$-dimensional $(ngeq 5)$ Riemannian manifolds of harmonic conformal curvature $(M,g)$ which are not conformally flat and admit a non-homothetic conformal change of metric $g mapstoar g$ such that $(M,ar
