On the moduli space of cubic threefolds and of some hyperkähler manifolds

, 2017
In a famous paper Allcock, Carlson and Toledo describe the moduli space of smooth cubic threefolds as a 10-dimensional ball quotient. We show how the 10-dimensional ball quotient is also the moduli space of hyperkähler fourfolds deformation equivalent to

A General Type of Almost Contact Manifolds [PDF]

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.

Hyperbolicity properties of moduli spaces of marked hyperkähler manifolds

International audienceWe study the hyperbolicity properties of moduli spaces of marked hyperkähler manifolds along directions corresponding to families having positivity properties for their Hodge bundle.

Separating manifolds in slow-fast systems [PDF]

, 2005
There are many applications that lead to models involving different timescales. For example, this is particularly the case for models of neurons, which involve dynamics of ionic channels across the cell membrane.

Reduction of coKähler and 3-cosymplectic manifolds [PDF]

The notions of coKähler manifolds and 3-cosymplectic manifolds are odd-dimensional analogues of the ones of Kähler manifolds and hyperKähler manifolds, respectively.

Kahler manifolds and their relatives [PDF]

, 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

Intersection Forms of Toric Hyperkähler Varieties

, 2003
This note proves combinatorially that the intersection pairing on the middle dimensional compactly supported cohomology of a toric hyperkähler variety is always definite, providing a large number of non-trivial L² harmonic forms for toric hyperkähler ...

On Hyperkähler manifolds of K3$^{[n]}$-type with large Picard number

Inspired by well-known examples of hyperkähler manifolds, we show that any hyperkähler manifold $X$ of K3$^{[n]}$-type with Picard number $ρ(X) \geq 4$ is always isomorphic to a moduli space of twisted stable sheaves on a K3 surface.
