Représentations P-adiques Et Normes Universelles

Let V be a crystalline p-adic representation of the absolute Galois group GK of an finite unramified extension K of Qp and T a lattice of V stable by GK . We prove the following result : Let FilV be the maximal sub-representation of V with Hodge-Tate weights strictly positive and FilT = T ∩ FilV . Then, the projective limit of the H g (K(μpn), T ) is equal up to torsion to the projective limit ...

Formes Modulaires Et Représentations -adiques

(2π)Γ(s)Lτ (s) is invariant under s 7→ 12 − s. The Ramanujan conjecture affirms that the roots of the polynomial Hp are of absolute value p −11/2 (i.e. that |τ(p)| < 2p). These properties, proven or conjectural, are similar to conjectural properties of zeta functions of algebraic varieties over Q. Suggested by this, in a first approximation, it is tempting to interpret the function Lτ as the ze...

Méthodes et fondements géométriques pour l’autocalibrage plan

We consider the problem of camera self-calibration, from images of a planar object with unknown Euclidean structure. The general case of possibly varying focal length is addressed. This problem is non-linear in general. One of our contributions is a non-linear approach, that makes abstraction of the (possibly varying) focal length, resulting in a computationally efficient algorithm. In addition...
