概要

In the late 1990's, R.Agemi proposed some problem related to (weak) null structure in nonlinear wave equations. In this talk, I will review recent progress on this problem and give an energy decay result under a suitable structural condition on the nonlinearity. This talk is based on a joint work with Akitaka Matsumura (Osaka) and Soichiro Katayama (Wakayama).
