Compactness and Structural Stability of Nonlinear Flows

Parabolic equations are usually regarded as not representable by a minimization principle; however results of Brezis and Ekeland [1], Nayroles [3] and Fitzpatrick [4] provide evidence of the contrary. This can also be extended to the parabolic flow of pseudo-monotone operators.

Compactness and stability of the dependence of the solution on the data and the potential can be proved on the basis of De Giorgi's notion of Gamma-convergence [2]. Here by compactness we mean that any sequence of potentials has a Gamma-convergent subsequence. Stability means that, if the data converge and the potentials Gamma-converge, then the sequence of solutions converges to a solution, up to extracting a subsequence, [5]. This was already known for stationary problems, and is here extended to evolutionary problems via a novel notion of evolutionary Gamma-convergence.

These results can be extended in several directions, including doubly-nonlinear parabolic inclusions.

This research is surveyed in [6].

Introduction to the twisted Alexander polynomial

The twisted Alexander polynomial was introduced independently by X.S. Lin and M.Wada in the 90s. It is a generalization of the classical Alexander polynomial by using linear representations and has become an effective tool in topology. In this talk, we will give an introduction to the twisted Alexander polynomial of knots and links.

Physics Colloquium: MRI, Hyperpolarized MRI and Metabolic MRI Wednesday, Oct 25
(4 p.m. - 5 p.m.)

Dr. Jian-Xiong Wang (UT Southwestern)

Magnetic Resonance Imaging (MRI) is widely used in clinic as a diagnostic modality for its non-invasive and non-radiation properties. In recent years, Hyperpolarized MRI, especially Hyperpolarized 13C Metabolite MRI has become a hot topic due to its possibility to reveal basic metabolism and cancer / disease metabolism. This presentation will briefly walk through the field to give the audiences in physics a general introduction about the technologies and possible applications of the Hyperpolarized 13C Metabolic MRI.
