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…

On the Frank-Wolfe algorithm for non-compact constrained optimization problems
O. P. Ferreira, W. S. Sosa
This paper is concerned with the Frank--Wolfe algorithm for a special class of {\it non-compact} constrained optimization problems. The notion of asymptotic cone is used to introdu…

Inexact Newton method with feasible inexact projections for solving constrained smooth and nonsmooth equations
Fabiana R. de Oliveira, Orizon P. Ferreira
In this paper, we propose a new method that combines the inexact Newton method with a procedure to obtain a feasible inexact projection for solving constrained smooth and nonsmooth…
