34 p, 280.4 KB Okutsu-montes representations of prime ideals of one-dimensional integral closures / Nart, Enric (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
This is a survey on Okutsu-Montes representations of prime ideals of certain one-dimensional integral closures. These representations facilitate the computational resolution of several arithmetic tasks concerning prime ideals of global fields.

18 p, 182.9 KB Exceptional singularities of codimension one holomorphic foliations / Brunella, Marco (Institut de Mathématiques de Bourgogne (França)) ; Perrone, Carlo (Università di Roma La Sapienza. Dipartimento di Matematica G. Castelnuovo)
We study some numerical properties of singularities of codimension one holomorphic foliations which can be analytically collapsed to one point. Some local and global dynamical consequences are deduced.

29 p, 239.8 KB Conical square functions and non-tangential maximal functions with respect to the gaussian measure / Maas, Jan (University of Bonn (Alemanya). Institute for Applied Mathematics) ; Neerven, Jan van (Delft University of Technology (Holanda). Delft Institute of Applied Mathematics) ; Portal, Pierre (Université Lille 1 (França). Laboratoire Paul Painlevé)
We study, in in L1(Rn;ƴ) with respect to the gaussian measure, non-tangential maximal functions and conical square functions associated with the Ornstein-Uhlenbeck operator by developing a set of techniques which allow us, to some extent, to compensate for the non-doubling character of the gaussian measure.

15 p, 135.3 KB Rational inner functions in the schur-agler class of the polydisk / Knese, Greg (University of Alabama)
Every two-variable rational inner function on the bidisk has a special representation called a unitary transfer function realization. It is well known and related to important ideas in operator theory that this does not extend to three or more variables on the polydisk. [...]

20 p, 189.2 KB Series parallel linkages / Cruickshank, James (National University of Ireland. School of Mathematics, Statistics and Applied Mathematics) ; McLaughlin, Jonathan (National University of Ireland. School of Mathematics, Statistics and Applied Mathematics)
We study spaces of realisations of linkages (weighted graphs) whose underlying graph is a series parallel graph. In particular, we describe an algorithm for determining whether or not such spaces are connected.

11 p, 131.6 KB Embedded curves and foliations / Movasati, Hossein (Instituto de Matemática Pura e Aplicada (Rio de Janeiro, Brasil)) ; Sad, Paulo (Instituto de Matemática Pura e Aplicada (Rio de Janeiro, Brasil))
We prove the existence of regular foliations with a prescribed tangency divisor in neighborhoods of negatively embedded holomorphic curves; this is related to a linearization theorem due to Grauert. We give also examples of neighborhoods which can not be linearized.

20 p, 213.7 KB A stability result for nonlinear neumann problems in reifenberg flat domains in Rn / Lemenant, Antoine (Université Paris Diderot - Paris 7) ; Milakis, Emmanouil (University of Cyprus. Department of Mathematics & Statistics)
In this paper we prove that if Ωk is a sequence of Reifenberg-flat domains in RN that converges to Ω for the complementary Hausdorff distance and if in addition the sequence Ωk has a "uniform size of holes", then the solutions uk of a Neumann problem of the form (. [...]

41 p, 530.9 KB Metric properties of outer space / Francaviglia, Stefano (Università Bologna. Dipartimento di Matematica) ; Martino, Armando (University of Southampton (Gran Bretanya). School of Mathematics)
We define metrics on Culler-Vogtmann space, which are an analogue of the Thurston metric and are constructed using stretching factors. In fact the metrics we study are related, one being a symmetrised version of the other. [...]

25 p, 208.9 KB Weighted inequalities for multivariable dyadic paraproducts / Chung, Daewon (University of New Mexico. Department of Mathematics and Statistics)
Using Wilson's Haar basis in Rn, which is different than the usual tensor product Haar functions, we define its associated dyadic paraproduct in Rn. We can then extend "trivially" Beznosova's Bellman function proof of the linear bound in L2(w) with respect to [w]A2 for the 1-dimensional dyadic paraproduct. [...]

19 p, 179.1 KB Bilinear littlewood-paley for circle and transference / Mohanty, Parasar (Indian Institute of Technology. Department of Mathematics and Statistics) ; Shrivastava, Saurabh (Indian Institute of Technology. Department of Mathematics and Statistics)
In this paper we have obtained the boundedness of bilinear Littlewood-Paley operators on the circle group T by using appropriate transference techniques. In particular, bilinear analogue of Carleson's Littlewood-Paley result for all possible indices has been obtained. [...]
