Il giorno 13 maggio 2025, alle ore 11:30, in SP2L, aula S. Rionero, del Dipartimento di Matematica e Applicazioni R. Caccioppoli dell'Università degli Studi di Napoli Federico II, il Prof. Kei Kobayashi, Department of Mathematics, Fordham University, terrà il seguente seminario:
"_Numerical approximation of stochastic di__ff__erential equations modeling subdi__ff__usion"_
Abstract: Standard Brownian motion composed with a random time change given by an inverse subordinator has been used to model subdiffusions, where particles spread more slowly than the classical Brownian particles. The time-changed Brownian motion is neither Markovian nor Gaussian, and standard procedures known for normal diffusions do not generally work. This talk gives an overview of the framework of numerical approximation schemes for the time-changed Brownian motion and its associated stochastic differential equations, along with the rates of convergence. This is based on joint work with Sixian Jin and Ernest Jum.
