{\Large GEOMETRIC EVOLUTION EQUATIONS}\\
Seminar, Fall 1997
\end{center}


We plan to present some recent papers in the general area
of geometric evolution equations of a `parabolic' nature.
The main topics of interest to the organizers are:
\vspace{.5cm}

\begin{itemize}
\item Curvature evolution of curves in the plane and on
surfaces (M.Gage, R.Hamilton, S.Angenent, G.Huisken);
\item Mean curvature flow: Asymptotic behavior of 
singularities (Huisken), evolution of entire graphs (Ecker-Huisken),
convergence of Allen-Cahn's equation to Brakke's flow (T. Ilmanen);
\item Center of mass of asymptotically flat spacetimes
and foliations by spheres of constant mean curvature
(Huisken-S.-T. Yau, R.Ye).
\end{itemize}
\vspace{.5cm}

We welcome suggestions from the participants on
additional recent work in this general area.
Graduate students with an interest in p.d.e./geometry
are encouraged to participate!

Prerequisites are
some experience with partial differential equations and some
familiarity with basic differential geometry.
