Critère pour l'intégralité des coefficients de Taylor des applications miroir

Eric Delaygue

We give a necessary and sufficient condition for the integrality of the Taylor coefficients of mirror maps at the origin. By mirror maps, we mean formal power series z.exp(G(z)/F(z…

Almost quarter-pinched Kähler metrics and Chern numbers

Martin Deraux, Harish Seshadri

We prove that compact Kähler manifolds whose sectional curvatures are close to 1/4-pinched have ratios of Chern numbers close to the corresponding ratios of a complex hyperbolic sp…

Binomial extensions of Simplicial ideals and reduction number

Minh Lam Ha, Marcel Morales

In this article, we define a class of binomial ideals associated to a simplicial complex. This class of ideals appears in the presentation of fiber cones of codimension 2 lattice i…

Ga-actions of fiber type on affine T-varieties

Alvaro Liendo

Let X be a normal affine T-variety, where T stands for the algebraic torus. We classify Ga-actions on X arising from homogeneous locally nilpotent derivations of fiber type. We ded…

Noise in Bose Josephson junctions: Decoherence and phase relaxation

G. Ferrini, D. Spehner, A. Minguzzi +1

Squeezed states and macroscopic superpositions of coherent states have been predicted to be generated dynamically in Bose Josephson junctions. We solve exactly the quantum dynamics…

Irrationality exponent and rational approximations with prescribed growth

Stéphane Fischler, Tanguy Rivoal

Let be a real irrational number. We are interested in sequences of linear forms in 1 and , with integer coefficients, which tend to 0. Does such a sequence exist such that t…
