Epsilon Nielsen fixed point theory

Fixed Point Theory and Applications, 2006
Let f:X→X be a map of a compact, connected Riemannian manifold, with or without boundary. For ∈>0 sufficiently small, we introduce an ∈-Nielsen number N∈(f) that is a lower bound for the number of fixed points of all self-maps of X ...

Biharmonic maps on V-manifolds

International Journal of Mathematics and Mathematical Sciences, 2001
We generalize biharmonic maps between Riemannian manifolds into the case of the domain being V-manifolds. We obtain the first and second variations of biharmonic maps on V-manifolds.

A note on geodesic and almost geodesic mappings of homogeneous Riemannian manifolds [PDF]

Opuscula Mathematica, 2005
Let \(M\) be a differentiable manifold and denote by \(\nabla\) and \(\tilde{\nabla}\) two linear connections on \(M\). \(\nabla\) and \(\tilde{\nabla}\) are said to be geodesically equivalent if and only if they have the same geodesics.

Estimates by gap potentials of free homotopy decompositions of critical Sobolev maps

Advances in Nonlinear Analysis, 2019
A free homotopy decomposition of any continuous map from a compact Riemannian manifold 𝓜 to a compact Riemannian manifold 𝓝 into a finite number maps belonging to a finite set is constructed, in such a way that the number of maps in this free homotopy ...

Empirical Means on Pseudo-Orthogonal Groups

Mathematics, 2019
The present article studies the problem of computing empirical means on pseudo-orthogonal groups. To design numerical algorithms to compute empirical means, the pseudo-orthogonal group is endowed with a pseudo-Riemannian metric that affords the ...

Critical mappings of Riemannian manifolds [PDF]

Transactions of the American Mathematical Society, 1979
We consider maps, from one Riemannian manifold to another, which are critical for all invariantly defined functionals on the space of maps. There are many such critical mappings, perhaps too numerous to suitably classify, although a characterization of sorts is provided.

Harmonic morphisms and subharmonic functions

International Journal of Mathematics and Mathematical Sciences, 2005
Let M be a complete Riemannian manifold and N a complete noncompact Riemannian manifold. Let ϕ:M→N be a surjective harmonic morphism. We prove that if N admits a subharmonic function with finite Dirichlet integral which is not harmonic, and ϕ has finite
