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

open access: yesAdvances 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 (

p-convex Riemannian manifolds

open access: yesInventiones Mathematicae, 1986
Let M be an n-dimensional compact connected Riemannian manifold with non- empty boundary. We say that the boundary is p-convex (where p is an integer with \(1\leq p\leq n-1)\) if at each point the sum of any p principal curvatures, defined with respect to the inward normal, is positive.

On Riemannian warped-twisted product submersions

open access: yesAIMS Mathematics
In this paper, we introduce the concepts of Riemannian warped-twisted product submersions and examine their fundamental properties, including total geodesicity, total umbilicity and minimality.
