On the period map for prime Fano threefolds of degree 10
O. Debarre, A. Iliev, L. Manivel
We prove that the deformations of a smooth complex Fano threefold X with Picard number 1, index 1, and degree 10, are unobstructed. The differential of the period map has two-dimen…
The largest eigenvalues of sample covariance matrices for a spiked population: diagonal case
Delphine Féral, Sandrine Péché
We consider large complex random sample covariance matrices obtained from "spiked populations", that is when the true covariance matrix is diagonal with all but finitely many eigen…
Lowest Weights in Cohomology of Variations of Hodge Structure (II)
Chris Peters, Morihiko Saito
Let be an irreducible complex analytic space with $j:U\into X$ an immersion of a smooth Zariski open subset, and let $\bV$ be a variation of Hodge structure of weight over…
The space of closed subgroups of
Benoit Kloeckner
The Chabauty space of a topological group is the set of its closed subgroups, endowed with a natural topology. As soon as , the Chabauty space of has a rather intricate…
On densest packings of equal balls of $\rb^{n}$ and Marcinkiewicz spaces
Gilbert Muraz, Jean-Louis Verger-Gaugry
We investigate, by "a la Marcinkiewicz" techniques applied to the (asymptotic) density function, how dense systems of equal spheres of $\rb^{n}, n \geq 1,$ can be partitioned at in…
Landau-Ginzburg/Calabi-Yau correspondence for quintic three-folds via symplectic transformations
Alessandro Chiodo, Yongbin Ruan
We compute the recently introduced Fan-Jarvis-Ruan-Witten theory of W-curves in genus zero for quintic polynomials in five variables and we show that it matches the Gromov-Witten g…
