On the Rational Hyperbolicity problem

Ricardo Mendes, Alessandro Minuzzo, Marco Radeschi

We prove that a compact simply connected manifold $M$ with a variationally complete $G$ -action satisfying certain mild conditions (e.g. trivial principal isotropy, or simply connec…

Reduction principles for proper actions

Leonardo Biliotti, Gustavo May Custodio, Alessandro Minuzzo

We study the core of a proper action by a Lie group $G$ on a smooth manifold $M$ , extending the construction for $G$ compact by Skjelbred and Straume. Moreover, we show that many p…

Complex Structures on Product Manifolds

Leonardo Biliotti, Alessandro Minuzzo

Let $M_{i}$ , for $i = 1, 2$ , be a KÃ¤hler manifold, and let $G$ be a Lie group acting on $M_{i}$ by KÃ¤hler isometries. Suppose that the action admits a momentum map $I^¼_{i}$ and let $N_i:=…
