27 p, 224.2 KB The Fourier transform in weighted Lorentz spaces / Sinnamon, Gord
Necessary conditions and sufficient conditions on weights u and w are given for the Fourier transform F to be bounded as a map between the Lorentz spaces Γq(w) and Λp(u). This may be viewed as a weighted extension of a result of Jodeit and Torchinsky on operators of type (1, ∞) and (2, 2). [...]

13 p, 163.0 KB Some compactness theorems of families of proper holomorphic correspondences / Ourimi, Nabil
In this paper we prove some compactness theorems of families of proper holomorphic correspondences. In particular we extend the well known Wong-Rosay's theorem to proper holomorphic correspondences. [...]

25 p, 212.5 KB Continuity properties for the maximal operator associated with the commutator of the Bochner-Riesz operator / Liu, Zongguang ; Lu, Guozhen ; Lu, Shanzhen
In this paper, we obtain some strong and weak type continuity properties for the maximal operator associated with the commutator of the Bochner-Riesz operator on Hardy spaces, Hardy type spaces and weak Hardy type spaces.

32 p, 265.7 KB Boundedness of the Weyl fractional integral on one-sided weighted Lebesgue and Lipschitz spaces / Ombrosi, S. (Universidad de Buenos Aires. Departamento de Matemática) ; De Rosa, L. (Universidad de Buenos Aires. Departamento de Matemática)
In this paper we introduce the one-sided weighted spaces L−w (β), −1 <β< 1. The purpose of this definition is to obtain an extension of the Weyl fractional integral operator I+α from Lp w into a suitable weighted space. [...]

We prove that the commutator [b, Iα], b ∈ BMO, Iα the fractional integral operator, satisfies the sharp, modular weak-type inequality f(x) tdx, where B(t) = tlog(e + t) and Ψ(t)=[tlog(e + tα/n)]n/(n−α). [...]

9 p, 136.3 KB On the geometric structure of the limit set of conformal iterated function systems / Käenmäki, Antti
We consider infinite conformal function systems on Rd. We study the geometric structure of the limit set of such systems. Suppose this limit set intersects some l-dimensional C1-submanifold with positive Hausdorff t-dimensional measure, where 0 <l<d and t is the Hausdorff dimension of the limit set. [...]

17 p, 181.6 KB Boundedness of sublinear operators on the homogeneous Herz spaces / Hu, Guoen
Some boundedness results are established for sublinear operators on the homogeneous Herz spaces. As applications, some new theorems about the boundedness on homogeneous Herz spaces for commutators of singular integral operators are obtained.

33 p, 276.3 KB Weighted two-parameter Bergman space inequalities / Wilson, J. Michael (University of Vermont. Department of Mathematics and Statistics)
For f , a function defined on Rd1 ×Rd2 , take u to be its biharmonic extension into R+ +1 × Rd2 +1 . In this paper we prove strong d1 + sufficient conditions on measures µ and weights v such that the inequality 1/q q ∇2 u dµ(x1 , x2 , y1 , y2 ) d +1 d +1 R+1 ×R+2 1/p ≤ f p v dx Rd1 ×Rd2 will hold for all f in a reasonable test class, for 1 < p ≤ 2 ≤ q < ∞.

15 p, 164.2 KB Virtually repelling fixed points / Buff, Xavier (Université Paul Sabatier)
In this article, we study the notion of virtually repelling fixed point. We first give a definition and an interpretation of it. We then prove that most proper holomorphic mappings f : U → V with U contained in V have at least one virtually repelling fixed point.

26 p, 231.7 KB Sums of an entire function in certain weighted L2-spaces / Brive, Bruno
We consider the functional equation f(z+σ)−f(z) = g(z) where σ is a complex number, f and g are entire functions of a complex variable z, with growth conditions. We prove the existence of certain types of solutions of this equation by an a priori estimate method in certain weighted L2-spaces.

23 p, 223.5 KB Comparison of Hausdorff measures with respect to the Euclidean and the Heisenberg metric / Balogh, Zoltán M. ; Rickly, Matthieu ; Serra Cassano, Francesco
We compare the Hausdorff measures and dimensions with respect to the Euclidean and Heisenberg metrics on the first Heisenberg group. The result is a dimension jump described by two inequalities. The sharpness of our estimates is shown by examples. [...]
