12:30 PM         Math 1150 Instructor Meeting      459 MSC

2:30 PM          Education Seminar                 459 MSC

3:30 PM          Calculus Seminar                  459 MSC
                 Mary Koshar, BGSU

                 Let's discuss strategies in the classroom for calculus
                 students.  I will share my experiences with my new and
                 revolutionary method.

11:30 AM         Statistics Seminar                459 MSC

                 Random spin-glass and rational portfolio selection
                 decisions

                 Models and methods developed in statistical physics
                 proved to be fruitful in studying complex system.  In
                 this talk, we discuss a classical portfolio selection
                 problem under nonlinear constraints, and show the
                 connection between the portfolio selection problem and
                 spin-glass problem in statistical physics.  Through
                 computational simulation, I will illustrate the concept
                 of random matrix problem and show that the optimal
                 rational solutions is actually exponentially
                 large. Thus, the concept of rational portfolio
                 selection may be challenged.

12:30 PM         Foundational Math Committee       400 MSC

1:00 PM          Graduate Committee Meeting        447 MSC

1:30 PM          Analysis Seminar                  459 MSC   
                 A. J. Wilhelm, BGSU
                 Several results from Sibilev

                 We will discuss parts of chapter six from
                 R.V. Sibilev's dissertation.

3:30 PM          Algebra Seminar                   459 MSC
                 Stephen Gagola, BGSU
                 Groups that admit triality

                 Here we will look deeper at the category of groups with
                 triality S3.  One of the most symmetrical examples
                 comes from the group D4(q).  Its Dynkin diagram has
                 four nodes with one node located at the center, and the
                 other three attached symmetrically. Here S3 acts on the
                 triality group by permuting the three legs trasitively.

3:30 PM          Colloquium                        459 MSC
                 Dr. Joseph Maher, CUNY College of Staten Island
                 Random walks on graphs and groups

                 We'll introduce random walks, starting with random
                 walks on the line and the plane. The study of these
                 goes back to Polya, and they can be used as elementary
                 models for both the stock market and the motion of
                 particles.  We'll review some basic properties of these
                 random walks, and discuss how they generalize to random
                 walks on other spaces, in particular, those arising in
                 the study of surfaces.
