Open Problem: Polynomial linearly-convergent method for geodesically convex optimization?

Christopher Criscitiello, David Martínez-Rubio, Nicolas Boumal

Let $f : M \to R$ be a Lipschitz and geodesically convex function defined on a $d$ -dimensional Riemannian manifold $M$ . Does there exist a first-o…

Accelerated Methods for Riemannian Min-Max Optimization Ensuring Bounded Geometric Penalties

David Martínez-Rubio, Christophe Roux, Christopher Criscitiello +1

In this work, we study optimization problems of the form $min_{x} max_{y} f (x, y)$ , where $f (x, y)$ is defined on a product Riemannian manifold $M \times N$ and i…
