• Endpoint solvability results for divergence form, complex elliptic equations 

    Mourgoglou, Michail (University of Missouri--Columbia, 2011)
    We consider divergence form elliptic equations Lu := ∇ • (A∇u) = 0 in the half space ℝn+1+ := {(x,t)∈ ℝn x (0,∞)}, whose coeffi cient matrix A is complex elliptic, bounded and measurable. In addition, we suppose that ...
  • Generalized local Tb theorem and applications 

    Grau de la Herran, Ana (University of Missouri--Columbia, 2012)
    The Tb theorem, like its predecessor, the T1 Theorem, is an L2 boundedness criterion, originally established by McIntosh and Meyer, and by David, Journé and Semmes in the context of singular integrals, but later extended ...
