Week of April 11-15, 2011 Monday, April 11, 2011 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. Tuesday, April 12, 2011 10:45 AM Math 1220 Instructor Meeting 459 MSC Wednesday, April 13, 2011 11:30 AM Statistics Seminar 459 MSC Haowen Xi, Physics Dept., BGSU 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. Thursday, April 14, 2011 11:30 AM Math 1210 Instructor Meeting 459 MSC Friday, April 15, 2011 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.
