After defining local and nonlocal operators, I'll introduce the Hilbert transform as a model nonlocal operator that we study. Throughout, I'll try to emphasize general points of interest/importance in the study of nonlocal operators (and more specifically, in the study of Calderón-Zygmund operators), with an eye toward studying the fractional Laplacian and other more complicated nonlocal operators in future talks.
