David Tewodrose: <b><a href='/seminar/531/'>Large-time behavior of the heat kernel on manifolds with non-negative Ricci curvature</a></b><br />
sala seminari, dipartimento di matematica di Pisa, 15:30<br /> </p>
<div style="font-size: smaller;"><p>The two formulae of the heat kernel on $\mathbb{R}^n$ and on the hyperbolic space$\mathbb{H}^n$ give a first example of the fact that the geometry of a space has an incidence on the heat kernel. On general manifolds, heat kernels are almost
never expressed by such explicit formulae. However, under some hypothesis
on the geometry of the manifold, nice upper or lower bounds of the heat
kernel can be obtained. In an article on 1986, P. Li used such bounds to
obtain a first result concerning the asymptotic behavior of the heat kernel
on manifolds with nonnegative Ricci curvature and maximal volume growth. In
2013, Xu obtained a similar result removing the maximal volume growth
hypothesis. The object of the seminar will be to present Li's and Xu's
works, stressing the use by Xu of Cheeger-Colding's theory.</p>

Matthew Gursky: <b><a href='/seminar/529/'>A formal Riemannian structure on the space of conformal metrics and some applications. </a></b><br />
Scuola Normale Superiore, Aula Tonelli, 16:00<br /> </p>
<div style="font-size: smaller;"><p>In this talk I will present some results from project with J. Streets (UC-Irvine), in which we define a formal
Riemannian metric on the set of metrics in a conformal class with positive (or negative) curvature. In the case of surfaces,
this metric has many interesting formal properties; for example the curvature is nonpositive and the Liouville energy is geodesically convex.
I will then talk about extensions to higher dimensions, especially 4-d, in which this construction has some interesting applications
to the fully nonlinear Yamabe problem.</p>
