Ricci curvature and Einstein metrics on aligned homogeneous spaces

Autor: Lauret, Jorge, Will, Cynthia

Let $M=G/K$ be a compact homogeneous space and assume that $G$ and $K$ have many simple factors. We show that the topological condition of having maximal third Betti number, in the sense that $b_3(M)=s-1$ if $G$ has $s$ simple factors, so called {\it

Isospectral spherical space forms and orbifolds of highest volume

Autor: Álzaga, Alfredo, Lauret, Emilio A.

We prove that $\operatorname{vol}(S^{d})/8$ is the highest volume of a pair of $d$-dimensional isospectral and non-isometric spherical orbifolds for any $d\geq5$. Furthermore, we show that $\operatorname{vol}(S^{2n-1})/11$ is the highest volume of a

Classical Myelo-Proliferative Neoplasms emergence and development based on real life incidence and mathematical modeling

Autor: Baranda, Ana Fernández, Bansaye, Vincent, Lauret, Evelyne, Mounier, Morgane, Ugo, Valérie, Méléard, Sylvie, Giraudier, Stéphane

Mathematical modeling offers the opportunity to test hypothesis concerning Myeloproliferative emergence and development. We tested different mathematical models based on a training cohort (n=264 patients) (Registre de la c\^ote d'Or) to determine the

Einstein metrics on homogeneous spaces $H\times H/\Delta K$

Autor: Lauret, Jorge, Will, Cynthia

Given any compact homogeneous space $H/K$ with $H$ simple, we consider the new space $M=H\times H/\Delta K$, where $\Delta K$ denotes diagonal embedding, and study the existence, classification and stability of $H\times H$-invariant Einstein metrics
