Self-exciting processes can be de ned in terms of a conditional intensity function in the equivalent forms (tjH t) = + Z t 0 g(t u)dN(u) = + X i:t i Splet21. sep. 2024 · The authors solve the self-excited Hawkes process by introducing a field master equation that transforms non-Markovian stochastic processes into Markov fields. This theory predicts a power law distribution of the activity rates with a non-universal exponent near criticality. gin shop malton

Splet1. That is quite simple to construct such a process by embedding stochastic differential equations, for example : d X t / X t = Y t. d W t and d Y t / Y t = d B t. with B t and W t two independent Brownian motions. Then X t is not Markovian, only the couple ( X t, Y t) is. You can construct plenty of examples this way. Regards.
