Analysis Seminar: Cancellative Sparse Domination
Speaker: José Conde Alonso, University of Madrid
Abstract: We present a sparse domination result for linear operators that respects the cancellation present in the input function. In particular, the H^1 \to L^1 boundedness of Calderón-Zygmund operators follows easily. Our method of proof provides a path to sparse domination results in situations where the weak type (1,1) endpoint is lacking. Based on joint work with Emiel Lorist (TU Delft) and Guillermo Rey (Universidad Autónoma de Madrid).
