Conformality on Semi-Riemannian Manifolds

Mediterranean Journal of Mathematics, 2015
The authors present an interesting study for a class \((C)\) of maps (conformal semi-Riemannian maps) between semi-Riemannian manifolds. The class \((C)\) contains semi-Riemannian submersions and isometric immersions. Some examples are given. A characterization is the following: Theorem 1.

Radar Target Detection with K-Nearest Neighbor Manifold Filter on Riemannian Manifold

Advances in Mathematical Physics
In this paper, we propose a K-nearest neighbor manifold filter on the Riemannian manifold and apply it to signal detection within clutter. In particular, the correlation and power of sample data in each cell are modeled as an Hermitian positive definite (

Harmonic Maps and Stability on f-Kenmotsu Manifolds

International Journal of Mathematics and Mathematical Sciences, 2008
The purpose of this paper is to study some submanifolds and Riemannian submersions on an f-Kenmotsu manifold. The stability of a ϕ-holomorphic map from a compact f-Kenmotsu manifold to a Kählerian manifold is proven.

Multiple solutions for nonlinear elliptic equations on Riemannian manifolds

Electronic Journal of Differential Equations, 2009
Let $(mathcal{M}, g)$ be a compact, connected, orientable, Riemannian $n$-manifold of class $C^{infty}$ with Riemannian metric $g$ $(ngeq 3)$. We study the existence of solutions to the equation $$ -varepsilon^2Delta_{g} u+V(x)u=K(x)|u|^{p-2}u ...

Comparative Studies of Some Topological Properties on Hyperspaces of Convex Bodies and Wasserstein Hyperspace Associated with Riemannian Manifold

Journal of Applied Sciences and Environmental Management
The topological properties of some Gromov–Hausdorff hyperspaces of convex bodies associated with Riemannian manifold have been investigated, however, the objective of this paper is to provide a comparative studies of some topological properties on ...

Einstein like -para Sasakian manifolds

Kuwait Journal of Science, 2013
Einstein like  -para Sasakian manifolds are introduced. For an  -para Sasakian manifold to be Einstein like, a necessary and sufficient condition in terms of its curvature tensor is obtained.
