BINGHAMTON GEOMETRY/TOPOLOGY SEMINAR<br><br>This week, we will have our first seminar of the semester as well as our first lecturer in our <b>Dean's Speaker Series in Geometry and Topology</b>, Dan Knopf of University of Texas at Austin.<br>
<br>
<br><i>Date:</i> Thursday, Sep 8, 2011<br>
<i>Time:</i> 4:30-5:30pm<br><i>Place:</i> Library North 2205 followed by coffee/tea in the Anderson Reading Room.<br>
<br>
<i>Speaker:</i> Dan Knopf (U Texas at Austin)<br><i>Title:</i> Ricci flow through singularities<br><em></em><i><br>Abstract:<br></i>We construct and describe smooth forward Ricci flow evolutions of
singular initial metrics resulting from rotationally symmetric
neckpinches, without performing an intervening surgery. In the
restrictive context of rotational symmetry, our construction gives
evidence in favor of Perelman's hope for a "canonically defined Ricci
flow through singularities." (This is joint work with Sigurd Angenent
and Cristina Caputo.)
