Self-Exciting Point Process

A self-exciting point process is a point process N such that

cov(N(s,t),N(t,u))>0

for s<t<u where here, cov denotes the covariance of the two quantities. Intuitively, a process is self-exciting if the occurrence of past points makes the occurrence of future points more probable.
