Equigeodesic vectors on compact homogeneous spaces with equivalent isotropy summands

Brian Grajales, Lino Grama

In this paper, we investigate equigeodesics on a compact homogeneous space $M = G / H .$ We introduce a formula for the identification of equigeodesic vectors only relying on the isotro…

On the sharpness of Strichartz estimates and spectrum of compact Lie groups

Duván Cardona, Brian Grajales, Michael Ruzhansky

We prove Strichartz estimates on any compact connected simple Lie group. In the diagonal case of Bourgain's exponents $p = q,$ we provide a new regularity order $s_{0}^{R} (p)$ in the…

Control of the Cauchy problem on Hilbert spaces: A global approach via symbol criteria

Duván Cardona, Julio Delgado, Brian Grajales +1

Let $A$ and $B$ be invariant linear operators with respect to a decomposition ${H_{j}}_{j \in N}$ of a Hilbert space $H$ in subspaces of finite dimension. We gi…
