Università di Napoli Federico II, 11:30<br /> </p>
<div style="font-size: smaller;"><p>Mathematics have been developed for generations, along several civilizations, to quantify, measure, explain and understand the surrounding world. Our modern society would not be possible without Mathematics. Mathematics and Language constitute, probably, the main distinguishing features of human nature. During its evolution, Mathematics got involved into, almost, all aspects of our life. The daily uses of Mathematics are numerous, and increasingly relevant. And this is particular the case in the context of modern Control Engineering. In this lecture, avoiding unnecessary technicalities, we shall present some aspects of the Mathematics of Control, describing some of the basic mathematical and computational tools, and also some relevant applications to the control of fluids and structures.</p>

Yuning Liu: <b><a href='/seminar/616/'>On the scaling limit of Onsager's molecular model for liquid crystals</a></b><br />
Sala Seminari Dipartimento di Matematica di Pisa, 17:15<br /> </p>
<div style="font-size: smaller;"><p>We study the small Deborah number limit of the Doi-Onsager equation for the dynamics of nematic liquid crystals. This is a Smoluchowski-type equation that characterizes the evolution of a number density function, depending upon both particle position and its orientation vector, which lies on the unit sphere. We prove that, in the low temperature regime, when the Deborah number tends to zero, the family of solutions with rough initial data near local equilibria will converge to a local equilibrium distribution prescribed by a weak solution of the harmonic map heat flow into the sphere. This flow is a special case of the gradient flow to the Oseen-Frank energy functional for nematic liquid crystals and the existence of its global weak solution was first obtained by Y.M Chen, using Ginzburg-Landau approximation. Our result can be considered as a kinetic proof of this classical result. The key ingredient is to show the strong compactness of the family of number density functions and the proof relies on the strong compactness of the corresponding second moment (or the Q-tensor), a spectral decomposition of the linearized operator near the limit local equilibrium distribution, as well as the energy dissipation estimate. This is a joint work with Wei Wang in Zhejiang university.</p>
