April 27 |
During Mathematics Awareness Week, the hallways of the GAB will proudly display posters on various mathematical topics. All such posters will be created by our undergraduates. |

This talk is designed for a popular audience and should be of special interest to our undergraduate majors and TAMS students.
Abstract:
We discuss the dynamical interaction of a central vortex flow with a plane
surface, a situation which occurs when a tornado makes contact with the
ground. This interaction leads to a secondary swirling flow within the
vortex, which can be of several different types depending on the coherence
of the vortex.
Among the possible kinds of induced secondary flows superimposed on the
main vortex, there are those with central updrafts (this type presumably
carried Dorothy to the Land of Oz). More surprisingly, however, there are
others which have a central downdraft, these being associated with a
cascade or fountain effect at the point of contact.
The latter motions are of particular interest in explaining the cascade
behavior observed in actual tornadoes, as seen in photographs and video
recordings taken by eyewitnesses. Some of these will be presented during
the lecture.

"The Nonlinear Schroedinger Equation:
Self-similar Solutions and Scattering Theory" Abstract: We consider two aspects of global solutions of the nonlinear Schroedinger equation, scattering and self-similar behavior, and discuss how they are related to each other, in some cases for the same solution. |

Just like a spelling bee, except with indefinite integrals! All
undergraduates are welcome to participate.
To learn how to register and other details about the 10th Annual Integration Bee, see the Integration Bee Web page. |
