Buongiorno,
*giovedì 18 Aprile alle ore 15:00,* nell'*aula 24 del Dipartimento di Scienze Statistiche, Sapienza* (ed. CU002, quarto piano) e online al link https://uniroma1.zoom.us/j/83831966596?pwd=U1pEclcrZzlFMXppcmVaL1FOaFUydz09 si terrà il seguente seminario:
*Speaker: Mariarosa Mazza (Università di Roma, Tor Vergata)*
*Titolo: Fractional derivatives and models: some numerical aspects* *Abstract:* Fractional derivatives are a well-established mathematical tool that has received much attention in recent decades due to their non-local behavior, proven to be useful in modeling anomalous diffusion present in various real-world phenomena. Examples include the generation and spread of electrical signals across biological excitable tissues, interactions between particles and fields within a plasma, and network dynamics in human environments. The improvement in describing these phenomena, however, results in a more challenging numerical treatment, requiring specialized strategies, e.g., in terms of discretization methods or numerical solvers. The aim of this talk is to give a little taste of the topic with a focus on the numerical linear algebra difficulties that it poses.
Grazie per l'attenzione, cordiali saluti. Luisa Beghin
