On projection mappings and the gradient projection method on hyperbolic space forms
Ronny Bergmann, Orizon P. Ferreira, Sandor Németh +1
This paper presents several new properties of the intrinsic -projection into -hyperbolically convex sets of -hyperbolic space forms, along with closed-form formulas for th…

Convexity of sets and quadratic functions on the hyperbolic space
Orizon Pereira Ferreira, Sándor Zoltán Németh, Jinzhen Zhu
In this paper some concepts of convex analysis on hyperbolic space are studied. We first study properties of the intrinsic distance, for instance, we present the spectral decomposi…
