High rank torus actions on contact manifolds
Gianluca Occhetta, Eleonora A. Romano, Luis E. Solá Conde +1
We prove LeBrun--Salamon conjecture in the following situation: if is a contact Fano manifold of dimension whose group of automorphisms is reductive of rank $\geq \max(2…

Characterizing the homogeneous variety F_4(4)
Gianluca Occhetta, Luis E. Solá Conde, Kiwamu Watanabe
In this paper we consider the -dimensional homogeneous variety of Picard number one , and provide a characterization of it in terms of its varieties of minimal ra…
