Query: Central Limit Theorem for Nonlinear Hawkes Processes   Hawkes process is a self-exciting point process with clustering effect whose
intensity depends on its entire past history. It has wide applications in
neuroscience, finance and many other fields. In this paper, we obtain a
functional central limit theorem for nonlinear Hawkes process. Under the same
assumptions, we also obtain a Strassen's invariance principle, i.e. a
functional law of the iterated logarithm.
