A mi-chemin entre analyse complexe et superanalyse / Bonneau, Pierre ; Cumenge, Anne
In the framework of superanalysis we get a functions theory close to complex analysis, under a suitable condition (A) on the real superalgebras in consi- deration (this condition is a generalization of the classical relation 1 + i2 = 0 in C). [...]

A geometric and stochastic proof of the twist point theorem / O'Neill, Michael D.
In this paper we will give a proof of the McMillan twist point theorem using geometry, potential theory and Ito's formula but not the Riemann mapping theorem.

Isolated singularities of binary differential equations of degree n / Fukui, T. ; Nuño-Ballesteros, J. J.
We study isolated singularities of binary differential equations of degree n which are totally real. This means that at any regular point, the associated algebraic equation of degree n has exactly n different real roots (this generalizes the so called positive quadratic differential forms when n = 2). [...]

An inner automorphism is only an inner automorphism, but an inner endomorphism can be something strange / Bergman, George M.
The inner automorphisms of a group G can be characterized within the category of groups without reference to group elements: they are precisely those au-tomorphisms of G that can be extended, in a functorial manner, to all groups H given with homomorphisms G ! H: (Precise statement in x1. [...]

Green currents for quasi-algebraically stable meromorphic self-maps of Pk / Nguyên, Viêt-Anh
We construct a canonical Green current Tf for every quasi-algebraically stable meromorphic self-map f of Pk such that its rst dynamical degree 1(f) is a simple root of its characteristic polynomial and that λ1(f) > 1: We establish a functional equation for Tf and show that the support of Tf is contained in the Julia set, which is thus non empty.

Sharp norm inequalities for commutators of classical operators / Cruz-Uribe, David (Trinity College. Department of Mathematics (Hartford, Estats Units)) ; Moen, Kabe (University of Alabama. Department of Mathematics)
We prove several sharp weighted norm inequalities for commutators of classical operators in harmonic analysis. We found suffcient Ap-bump conditions on pairs of weights (u; v) such that [b; T], b 2 BMO and T a singular integral operator (such as the Hilbert or Riesz transforms), maps Lp(v) into Lp(u). [...]

Bundary values in range spaces of co-analytic truncated toeplitz operators / Hartmann, Andreas ; Ross, William T.
Functions in backward shift invariant subspaces have nice analytic continuation properties outside the spectrum of the inner function de ning the space. Inside the spectrum of the inner function, Ahern and Clark showed that under some distribution condition on the zeros and the singular measure of the inner function, it is possible to obtain non-tangential boundary values of every function in the backward shift invariant subspace as well as for their derivatives up to a certain order. [...]

Asymptotics for the minimum riesz energy and best-packing on sets of finitie packing premeasure / Borodachov, Sergiy
We show that for every compact set A ⊂ Rm of finite α -dimensional packing premeasure 0 < α ≤m, the lower limit of the normalized discrete minimum Riesz s-energy (s > α ) coincides with the outer measure of A constructed from this limit by method I. [...]
