报告摘要:We study the dynamics of a delay induced non-local free boundary problem. We obtain a rather complete description of its long-time dynamical behaviour, which is shown to follow a spreading-vanishing dichotomy. When spreading persists, we show that the asymptotic spreading speed of the free boundary is uniquely determined by an associated non-local elliptic problem over the half line.
