    Compactness of the Bloom sparse operators and applications
    Seminar - 11th Floor Lecture Hall
    • Speaker
    • Naga Manasa Vempati, Georgia Institute of Technology
    • Session Chair
    • Sergei Treil, Brown University
    Abstract
    We discuss the characterization of compactness for the sparse operator (associated with symbol in weighted VMO space) in the two-weight setting on the spaces of homogeneous type. As a direct application we obtain the compactness characterization for the maximal commutators with respect to the weighted VMO functions and the commutator of Calderon–Zygmund operators on the homogeneous spaces. We will look at the applications of this approach to multilinear Bloom setting.

    Optimal estimates for the conductivity problems with closely spaced inclusions of high contrast
    Post Doc/Graduate Student Seminar - 11th Floor Lecture Hall
    • Zhuolun Yang, Brown University
    Abstract
    In this talk, I will describe an elliptic PDE that models electric conduction, and the electric field concentration phenomenon between closely spaced inclusions of high contrast. In the first part, I will present some results on the insulated conductivity problem (jointly with Hongjie Dong and Yanyan Li). We obtained an optimal gradient estimate in terms of the distance between inclusions. This solved one of the major open problems in this area. In the second part, I will discuss a recent work regarding optimal estimates for higher derivatives of the conductivity problem with circular inclusions in 2D, when the relative conductivities of inclusions have different signs (Jointly with Hongjie Dong). This improves a recent result of Ji and Kang.

    Wavelet representation and Sobolev regularity of quasiconformal mappings on domains
    Seminar - 11th Floor Lecture Hall
    • Francesco Di Plinio, Università degli Studi di Napoli ``Federico II"
    Abstract
    This work devises a new smooth representation formula for the compression of CZ operators on domains. As a first order consequence of this representation, we obtain a weighted, sharply quantified T(1)-type theorem on Sobolev spaces. Previous results of Prats and Prats-Tolsa are limited to unweighted bounds for convolution-type operators. Our weighted Sobolev inequalities are subsequently applied to obtain quantitative regularity results for solutions to the Beltrami equation with symbol in the critical class W^{k,2}(Omega). Alll past results, due to Prats among others, based on the Iwaniec scheme are of qualitative nature. Talk is based on current and ongoing joint work with Walton Green and Brett Wick (WUSTL)
