On the mod - p cohomology of Out(F_{2(p-1)}
Henry Glover, Hans-Werner Henn
We study the mod-p cohomology of the group Out(F_n) of outer automorphisms of the free group F_n in the case n=2(p-1) which is the smallest n for which the p-rank of this group is…
The homotopy of the K(2)-local Moore spectrum at the prime 3 revisited
Hans-Werner Henn, Nasko Karamanov, Mark Mahowald
In this paper we use the approach introduced in an earlier paper by Goerss, Henn, Mahowald and Rezk in order to analyze the homotopy groups of L_{K(2)}V(0), the mod-3 Moore spectru…
Generalized Demailly-Semple jet bundles and holomorphic mappings into complex manifolds
Gianluca Pacienza, Erwan Rousseau
Motivated by the Green-Griffiths conjecture, we study maximal rank holomorphic maps from $\C^p$ into complex manifolds. When such maps should in principle be more tractable t…
Obstructions to the existence of monotone Lagrangian embeddings into cotangent bundles of manifolds fibered over the circle
AGNès Gadbled
We extend constructions and results of Damian to get topological obstructions to the existence of closed monotone Lagrangian embeddings into the cotangent bundle of a space which i…
Une classe d'espaces préhomogènes de type parabolique faiblement sphériques
Iris Muller
For absolutely simple, finite-dimensional Lie algebras g of rank at least 2, defined over a local field of characteristic 0 and admitting a graduation: g=g(-2)+g(-1)+g(0)+g(1)+g(2)…
Adaptive asymptotically efficient estimation in heteroscedastic nonparametric regression via model selection
Leonid Galtchouk, Serguey Pergamenshchikov
The paper deals with asymptotic properties of the adaptive procedure proposed in the author paper, 2007, for estimating a unknown nonparametric regression. We prove that this proce…
On asymptotic normality of sequential LS-estimates of unstable autoregressive processes
Leonid Galtchouk, Victor Konev
For estimating the unknown parameters in an unstable autoregressive AR(p), the paper proposes sequential least squares estimates with a special stopping time defined by the trace o…
Quadratic functors on pointed categories
Manfred Hartl, Christine Vespa
We study polynomial functors of degree 2, called quadratic, with values in the category of abelian groups , and whose source category is an arbitrary category $\C$ with null ob…
Hyperbolicity of geometric orbifolds
Erwan Rousseau
We study complex hyperbolicity in the setting of geometric orbifolds introduced by F. Campana. Generalizing classical methods to this context, we obtain degeneracy statements for e…
Sur l'homologie des groupes orthogonaux et symplectiques à coefficients tordus
Aurélien Djament, Christine Vespa
We compute the stable homology of orthogonal and symplectic groups over a finite field k with coefficients coming from an usual endofunctor F of k-vector spaces (exterior, symmetri…
Some metrics on Teichmüller spaces of surfaces of infinite type
Lixin Liu, Athanase Papadopoulos
Unlike the case of surfaces of topologically finite type, there are several different Teichmüller spaces that are associated to a surface of topological infinite type. These Teichm…
On the distance between separatrices for the discretized pendulum equation
Hocine Sellama
We consider the discretization q(t+ε)+q(t-ε)-2q(t)=ε^{2}\sin\big(q(t)\big), a small parameter, of the pendulum equation ; in system form, we have the discr…
Adaptive nonparametric estimation in heteroscedastic regression models. Part 1: Sharp non-asymptotic Oracle inequalities
Leonid Galtchouk, Serguey Pergamenshchikov
An adaptive nonparametric estimation procedure is constructed for the estimation problem of heteroscedastic regression when the noise variance depends on the unknown regression. A…
Adaptive sequential estimation for ergodic diffusion processes in quadratic metric. Part 2: Asymptotic efficiency
Leonid Galtchouk, Serguey Pergamenshchikov
Asymptotic efficiency is proved for the constructed in part 1 procedure, i.e. Pinsker's constant is found in the asymptotic lower bound for the minimax quadratic risk. It is shown…
Adaptive nonparametric estimation in heteroscedastic regression models. Part 2: Asymptotic efficiency
Leonid Galtchouk, Serguey Pergamenshchikov
The paper deals with asymptotic properties of the adaptive procedure proposed in the author paper (2007) for estimation of unknown nonparametric regression. We prove that this proc…
Invariant differential operators and an infinite dimensional Howe-type correspondence. Part I: Structure of the associated algebras of differential operators
Hubert Rubenthaler
If is a non degenerate quadratic form on ${\bb C}^n$, it is well known that the differential operators , , and , where is the Euler…
