41 p, 515.1 KB Extrapolation methods and Rubio de Francia's extrapolation theorem / Martín i Pedret, Joaquim (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Milman, Mario (Florida Atlantic University. Department of Mathematics)
We develop a general framework to study extrapolation of inequalities.

77 p, 1.1 MB Gradient of the single layer potential and quantitative rectifiability for general Radon measures / Puliatti, Carmelo (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
We identify a set of sufficient local conditions under which a significant portion of a Radon measure μ on with compact support can be covered by an uniformly n-rectifiable set, at the level of a ball such that . [...]

49 p, 554.4 KB Two-weight commutator estimates : general multi-parameter framework / Airta, Emil (University of Helsinki. Department of Mathematics and Statistics)
We provide an explicit technical framework for proving very general two-weight commutator estimates in arbitrary parameters. The aim is to both clarifyexisting literature, which often explicitly focuses on two parameters only, and toextend very recent results to the full generality of arbitrary parameters. [...]

35 p, 488.5 KB The boundedness of multilinear Calderón-Zygmund operators on weighted and variable Hardy spaces / Cruz-Uribe, David (University of Alabama. Department of Mathematics) ; OFS ; Moen, Kabe (University of Alabama. Department of Mathematics) ; Van Nguyen, Hanh (University of Alabama. Department of Mathematics)
We establish the boundedness of the multilinear Calderon{Zygmund operators from a product of weighted Hardy spaces into a weighted Hardy or Lebesgue space. Our results generalize to the weighted setting results obtained by Grafakos and Kalton [18] and recent work by the third author, Grafakos, Nakamura, and Sawano [20]. [...]

46 p, 511.8 KB Multilinear singular integrals / Thiele, Christoph M. (University of California. Department of Mathematics)
We survey the thoery of multilinear singular integral operators with modulation symmetry. The basic example for this theory is the bilinear Hilbert transform and its multilinear variants. We outline a proof of boundedness of Carleson's operator which shows the close connection of this operator to multilinear singular integrals. [...]

12 p, 154.8 KB Singular integrals on Sierpinski gaskets / Chousionis, Vasilis (University of Helsinki. Department of Mathematics and Statistics)
We construct a class of singular integral operators associated with homogeneous Calderón-Zygmund standard kernels on d-dimensional, d < 1, Sierpinski gaskets Ed. These operators are bounded in L2(μd) and their principal values diverge μd almost everywhere, where μd is the natural (d-dimensional) measure on Ed.

14 p, 159.1 KB Operator valued BMO and commutators / Blasco de la Cruz, Oscar (Universitat de València. Departament de Matemàtiques)
If E is a Banach space, b ∈ BMO(Rn, L(E) and T is a L(E)-valued Calderón-Zygmund type operator with operator-valued kernel k, we show the boundedness of the commutator Tb(f) = bT(f) − T(bf) on Lp(Rn,E) for 1 < p < ∞ whenever b and k verify some commuting properties. [...]

58 p, 348.9 KB Carleson's theorem : proof, complements, variations / Lacey, Michael T.
Carleson's Theorem from 1965 states that the partial Fourier sums of a square integrable function converge pointwise. We prove an equivalent statement on the real line, following the method developed by the author and C. [...]
