Webt is the natural ltration of the process, is called an M-variate Hawkes process with exponential decays on [0;1). Remark 1.1. The intensity for a multivariate Hawkes process on (1 ;1) can be written in the vector form as (Hawkes, 1971, p.86, (20)) (t) = + Z t 1 (t u)dN(u): where is an M-by-Mmatrix. Assuming stationarity, we have (Hawkes, 1971 ... WebThe Hawkes process is a self-exciting simple point process ﬁrst introduced by A. Hawkes in 1971 ([15, 16]). The future evolution of a self-exciting point process is inﬂuenced by the timing of past events. The process is non-Markovian except for some very special cases …
