Salvatore Stuvard (The University of Texas at Austin): <b><a href='/seminar/809/'>Mean curvature flow with prescribed boundary: a dynamical approach to Plateau’s problem</a></b><br />
Zoom seminar, 14:30<br />
</p>
<div style="font-size: smaller;"><p>The Brakke flow is a measure-theoretic generalization of the mean curvature flow which describes the evolution by mean curvature of surfaces with singularities. In the first part of the talk, I am going to discuss global existence and large time asymptotics of solutions to the Brakke flow with fixed boundary when the initial datum is given by any arbitrary rectifiable closed subset of a convex domain which disconnects the domain into finitely many "grains". Such flow represents the motion of material interfaces constrained at the boundary of the domain, and evolving towards a configuration of mechanical equilibrium according to
the gradient of their potential energy due to surface tension. In the second part, I will focus on the case when the initial datum is already in equilibrium (a generalized minimal surface): I will prove that, in presence of certain singularity types in the initial datum, there always exists a non-constant solution to the Brakke flow. This suggests that the class of dynamically stable minimal surfaces, that is minimal surfaces which do not move by Brakke flow, may be worthy of further study within the investigation on the regularity properties of minimal surfaces. Based on joint works with Yoshihiro Tonegawa (Tokyo Institute of Technology).</p>

Antonio DeSimone: <b><a href='/seminar/804/'>Motilità biologica e robot bio-ispirati: nuove sfide e opportunità e per la matematica</a></b><br />
Dipartimento di Matematica di Pisa (online), 17:00<br />
</p>
<div style="font-size: smaller;"><p>La biologia è una ricca fonte di ispirazione, anche per la ricerca di nuovi materiali, nuove forme e strategie di movimento, dispositivi mobili e adattabili con nuove funzionalità, strutture architettoniche biomorfe.
Di straordinario interesse sono gli organismi unicellulari: invisibili ad occhio nudo data le loro dimensioni microscopiche, essi offrono nuove e sorprendenti soluzioni alla domanda su come controllare la forma. Le loro insolite strategie di morphing possono ispirare soluzioni innovative a problemi nella robotica, nell'ingegneria biomedica e strutturale, in architettura.
</p>
<p>Negli ultimi anni, abbiamo studiato la locomozione e il controllo della forma di un protista unicellulare (Euglena gracilis) utilizzando una vasta gamma di strumenti che comprende la meccanica teorica e computazionale, la modellizzazione matematica, la sperimentazione fisica e le osservazioni al microscopio, la produzione di prototipi <a href='1'>1</a>. E. gracilis è particolarmente interessante come organismo unicellulare modello perché può adottare diverse strategie di motilità: nuota usando la propulsione flagellare, oppure striscia grazie a cambiamenti di forma di tutto il corpo (moto ameboide associato alla propagazione di onde peristaltiche). Analizzeremo i nostri risultati più recenti all'interno di questo filone di ricerca, sottolineando le possibilità per nuovi sviluppi e approfondimenti.
