The sharp local well-posedness result for generic nonlinear wave equations was proved in my work with Smith about 20 years ago. Around the same time, it was conjectured that, for problems satisfying a suitable nonlinear null condition, the local well-posedness threshold can be improved. In this talk I will describe the first result establishing this conjecture for a good model. This is joint work with Albert Ai and Mihaela Ifrim.
