For a sparse multivariate Hawkes process, let denote the cross-area between coordinates and over a time horizon , and let the associated excitation graph enco…
Chen–Hermite Gaussianity conjecture. Then must be a Gaussian process. This would establish joint Gaussianity from Gaussian single-increment laws and the Chen–He…
Variation-constant conjecture. For , the -th variation along deterministic partitions differs from that along uniform Lebesgue partitions, more precisely,
Pure rough path signature-tail asymptotics conjecture. For every pure -rough path, the tail asymptotics equals its local -variation, namely
