The study of fractional and nonlocal partial differential equations has seen a renewed interest in recent years, as can be seen for example in the work of Caffarelli and Silvestre, as well as Sire, Valdinoci and others. In fact, the notion is much older, dating at least to work of Calderon and Zygmund. In this talk, I will review some of the history and relevant ideas, as well as discuss recent work on the subject done in collaboration with Tien-Tsan Shieh.
