Sasaki structures distinguished by their basic Hodge numbers

D. Kotschick, G. Placini

In all odd dimensions $\geq 5$ we produce examples of manifolds admitting pairs of Sasaki structures with different basic Hodge numbers. In dimension $5$ we prove more precise resu…

Maximally non-integrable almost complex structures: an $h$ -principle and cohomological properties

Rui Coelho, Giovanni Placini, Jonas Stelzig

We study almost complex structures with lower bounds on the rank of the Nijenhuis tensor. Namely, we show that they satisfy an $h$ -principle. As a consequence, all parallelizable m…

Sasakian immersions of Sasaki-Ricci solitons into Sasakian space forms

Giovanni Placini

Let $(g, X)$ be a Sasaki-Ricci soliton on a Sasakian manifold $S$ . We prove that if $(S, g)$ admits a local Sasakian immersion in a Sasakian space form $S (N, c)$ of constant $ϕ$ -secti…
