Multiple Poisson-Dirichlet diffusions on generalized Kingman simplices
Cristina Costantini, Matteo Ruggiero
We construct a new class of infinite-dimensional diffusions with values in a generalized Kingman simplex with finitely many marks. The model describes the temporal evolution of the…

Filtering coupled Wright-Fisher diffusions
Chiara Boetti, Matteo Ruggiero
Coupled Wright-Fisher diffusions have been recently introduced to model the temporal evolution of finitely-many allele frequencies at several loci. These are vectors of multidimens…
