VIGRE Graduate Student Seminar
2:00p.m., Room 304
Speaker: Jason Cantarella, University of Georgia
Title of talk: A Practical Introduction to Mathematical Visualization
Abstract: This talk (delayed from January) will be an introduction to the art and science of producing helpful illustrations for your mathematical writing. We will cover software for producing images, including those images in TeX files, and labelling the resulting figures in TeX. In addition, we will talk about criteria for judging effective images and the process by which useful visualizations are created. Note that this will NOT cover the Summer Undergraduate Research experience on "Mathematics and Visualization", which will be discussed in a Math Club talk on Thursday, February 12, at 4 pm.

Special Seminar in Analysis
Georgia Tech Instructional center, Room 219
Speaker: Mariangel Alfonseca, Georgia Tech
Titleof talk: Maximal functions along directions in R^2: an almost-orthogonality principle and its aplications

Wavelet Analysis
2:00p.m., Room 326
Speaker: Jie Zhou, University of Georgia
Title of talk: Compactly supported symmetric scaling functions

WEDNESDAY, February 11, 2004

Berkovich Spaces Seminar
11:00a.m., Room 410
Organizers: Matthew Baker and Robert Rumely

Algebra
2:30p.m., Room 322
Speaker: Dave Benson, University of Georgia
Title of talk: Spectral sequences, continued.
Abstract: I shall continue talking about spectral sequences where Jon Carlson left off. This means that I shall continue
talking about the spectral sequence of a double complex, and give some examples of applications. The examples will principally be based around the spectral sequence of a group extension.

Colloquium
3:30p.m., Room 304
Speaker: Markus Hirschberger, University of Eichstaett-Ingolstadt
Title of talk: Efficiency Concepts for Stochastic Linear Multiobjective Programs
Abstract: The notions of "efficiency" and "proper efficiency" for deterministic multiobjective programs are introduced. These are extended to stochastic programs by introducing the "Expected value-variance efficiency" and "efficiency in probability" concepts, which are illustrated on the portfolio selection problem. Assuming that all objective vectors are normally distributed, we discuss the three most important questions for the stochastic linear multiobjective program: We show the relations between the various efficiency concepts, give a proof scheme for the arcwise connectedness of the efficient sets, and present a computation procedure of polynomial complexity.
