Kähler-Einstein metrics on toric Fano manifolds and connections to Optimal Transport
, 2021 We introduce the problem of finding a Kähler-Einstein metric on a Kähler manifold and specifically on a Fano manifold. We restrict to the class of toric complex manifolds where the symmetry can be used to reduce the resulting partial differential ...

Kahler manifolds and their relatives
, 2010 Let M1 and M2 be two K¨ahler manifolds. We call M1 and M2 relatives if they share a non-trivial K¨ahler submanifold S, namely, if there exist two holomorphic and isometric immersions (K¨ahler immersions) h1 : S → M1 and h2 : S → M2. Moreover, two K¨ahler

A splitting theorem for Kähler manifolds with constant eigenvalues of the Ricci tensor
, 2001 International audienceIt is proved that a compact Kähler manifold whose Ricci tensor has two distinct constant non-negative eigenvalues is locally the product of two Kähler–Einstein manifolds.

A General Type of Almost Contact Manifolds
Among almost contact manifolds Sasakian manifolds, Kenmotsu manifolds (called also “a certain class of almost contact manifolds”) and cosymplectic manifolds have been studied by many authors.

New examples of strictly almost Kähler manifolds
, 1983 A parametrized family of non-Kähler almost Kähler manifolds is constructed as the product of solvable Lie groups with almost cosymplectic structures. A family of compact strictly almost Kähler manifolds whose cohomology is consistent with that of Kähler ...

Quasi-Einstein metrics on hypersurface families
, 2013 We construct quasi-Einstein metrics on some hypersurface families. The hypersurfaces are circle bundles over the product of Fano, Kähler-Einstein manifolds.
