14 p, 154.3 KB Trace and determinant in Jordan-Banach algebras ALGEBRAS / Aupetit, Bernard ; Maouche, Abdelaziz
Using an appropriate definition of the multiplicity of a spectral value, we introduce a new definition of the trace and determinant of elements with finite spectrum in Jordan-Banach algebras. We first extend a result obtained by J. [...]

9 p, 147.0 KB On the Hodge theory of the symmetric powers of a curve / Baño Rollin, Sebastian del
We describe the polarised Hodge structure on the symmetric powers of a smooth projective curve.

22 p, 199.2 KB Distribution-valued iterated gradient and chaotic decompositions of Poisson jump times functionals / Privault, Nicolas
We define a class of distributions on Poisson space which allows to iterate a modification of the gradient of [1]. As an application we obtain, with relatively short calculations, a formula for the chaos expansion of functionals of jump times of the Poisson process.

27 p, 231.8 KB Fatou and Korányi-Vági type theorems on the minimal ball / Anh, Nguyên Viêt
In this paper we develop the Hp (p [greater than or equal] 1) theory on the minimal ball. After identifying the admissible approach regions, we establish theorems of Fatou and Korányi-Vági type on this ball.

20 p, 193.5 KB Density estimates on a parabolic spde / Márquez-Carreras, D. ; Mellouk, M.
We consider a general class of parabolic spde's [formula] with (t, x) [member of] [0, T]×[0, 1] and [epsilon]Wt,x, [epsilon] > 0, a perturbed Gaussian space-time white noise. For (t, x) [member of] (0, T]×(0, 1) we prove the called Davies and Varadhan-Léandre estimates of the density p[epsilon]t,x of the solution u[epsilon]t,x.

22 p, 1.1 MB Stable rational cohomology of automorphism groups of free groups and the integral cohomology of moduli spaces of graphs / Jensen, Craig A.
It is not known whether or not the stable rational cohomology groups H*(Aut(F[infinity]);Q) always vanish (see Hatcher in [5] and Hatcher and Vogtmann in [7] where they pose the question and show that it does vanish in the first 6 dimensions). [...]

20 p, 201.0 KB Two weighted inequalities for convolution maximal operators / Bernardis, A. L. (Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET). Instituto de Matemática Aplicada del Litoral) ; Martín-Reyes, F. J. (Universidad de Málaga. Departamento de Análisis Matemático)
Let ϕ: R → [0, ∞) an integrable function suchthat ϕχ(−∞,0) = 0 and ϕ is decreasing in (0, ∞). Let τhf(x) = f(x − h), with h ∈ R \ {0} and fR(x) = 1 R f( x R ), with R > 0. In this paper we characterize the pair of weights (u, v) such that the operators Mτhϕf(x) = supR>0 |f| ∗ [τhϕ]R(x) are of weak type (p, p) withrespect to (u, v), 1 <p< ∞.

13 p, 148.4 KB A Note on nonexistence of radial solutions to semilinear elliptic inequations / Guedda, Mohammed
We study the nonexistence result of radial solutions to -[Delta]u + [formula] posed in B or in B \ {0} where B is the unit ball centered at the origin in RN, N [greater than or equal] 3. Moreover, we give a complete classification of radial solutions to the problem [formula]. [...]

25 p, 244.9 KB Two problems associated with convex finite type domains / Iosevich, Alexander ; Sawyer, Eric ; Seeger, Andreas
We use scaling properties of convex surfaces of finite line type to derive new estimates for two problems arising in harmonic analysis. For Riesz means associated to such surfaces we obtain sharp Lp estimates for p &amp;amp;gt; 4, generalizing the Carleson-Sjölin theorem. [...]

Département de Mathématiques) ; Ghorbel, Amira (Faculté des Sciences de Sfax (Tunísia). Département de Mathématiques) ; Hamrouni, Hatem (Faculté des Sciences de Sfax (Tunísia). Département de Mathématiques)
Let G be an exponential solvable Lie group, H and A two closed connected subgroups of G and [sigma] a unitary and irreducible representation of H. We prove the orbital spectrum formula of the Up-Down representation [rho](G,H, A, [sigma]) = IndGH [sigma] A . [...]

19 p, 214.1 KB Sur le rang d'une extension pro-p-libre d'un corps de nombres / Lannuzel, Arthur
For an algebraic number field k and a prime number p (if p = 2, we assume that µ4 [contained in] k), we study the maximal rank [rho]k of a free pro-p-extension of k. We give various interpretations of 1+r2(k)-[rho]k. [...]

15 p, 173.1 KB A Nonlinear eigenvalue problem with indefinite weights related to the Sobolev trace embedding / Fernández Bonder, Julián ; Rossi, Julio D.
In this paper we study the Sobolev trace embedding W1,p([omega]) --&amp;amp;gt;LpV ([delta omega]), where V is an indefinite weight. This embedding leads to a nonlinear eigenvalue problem where the eigenvalue appears at the (nonlinear) boundary condition. [...]
