Mathematics Colloquium: Geometric Averaging Operators and Point Configurations
Date and time

Description

Finding and understanding patterns in data sets is of significant importance in many applications.  One example of a simple pattern is the distance between data points, which can be thought of as a 2-point configuration.  Two classic questions, the Erdos distinct distance problem, which asks about the least number of distinct distances determined by N points in the plane, and its continuous analog, the Falconer distance problem, explore that simple pattern.  When studying the continuous analogues geometric averaging operators, such as the spherical averaging operator, arise naturally.  Questions similar to the Erdos distinct distance problem and the Falconer distance problem can also be posed for more complicated patterns such as triangles, which can be viewed as 3-point configurations.  In this talk Dr. Palsson will give a brief introduction to the motivating point configuration questions and then report on some novel geometric averaging operators and their mapping properties.
