Student Talk Series: Kelly Bickel, Bucknell University, Thursday, September 3rd in Olin 268 @ noon

Title: Geometry, Meet Origami Abstract: In this talk, we will go back in time to the ancient Greeks (or at least your high school geometry class) and take a good look at what we can draw with a compass and straight-edge. The answer is “Not Much!,” at least when compared to what a little paper folding will get us. Come prepared to trisect some angles, double some cubes, and scoff at the circle squarers.

The Bucknell Pre-calculus Requirement

College-level mathematics is exciting and empowering, and the Mathematics Department wants your experience to begin in the best way possible!  We are providing and requiring a 6-week online preparation course—the ALEKS Prep. for Calculus—for all students who will take MATH 201.  Results from previous years show that working through this online course will get you started on the path to success in college calculus. The Prep. for Calculus course will be available starting July 1. The deadline for completion for Fall Calculus enrollment is Aug. 28; we recommend you start by Aug 1. Students with a Spring Calculus enrollment may […]

Distinguished Visiting Professor Talk Series: Sergi Elizalde, Dartmouth College, November 24th @4pm in Olin 372

Title: Consecutive patterns in permutations   Abstract: An occurrence of a consecutive pattern sigma in a permutation pi is a subsequence of adjacent entries of pi in the same relative order as the entries of sigma. For example, occurrences of the consecutive pattern 21 are descents, and alternating permutations are those that avoid the consecutive patterns 123 and 321. The systematic study of consecutive patterns in permutations started over a decade ago.  More recently, consecutive patterns have become relevant in the study of one-dimensional dynamical systems, and they are useful in creating tests to distinguish random from deterministic time series. We […]

Distinguished Visiting Professor Talk Series: Eva A. Gallardo Gutierrez, Universidad Complutense de Madrid, October 23rd @ 4pm in Olin 372

Title: Rota’s Universal Operators Abstract: The Invariant Subspace Problem for Hilbert spaces is a long-standing question and the use of universal operators in the sense of Rota has been one tool for studying the problem. The best known universal operators have been adjoints of analytic Toeplitz operators or unitarily equivalent to them. We present many examples of Toeplitz operators whose adjoints are universal operators and exhibit some of their common properties. Some ways in which the invariant subspaces of these universal operators interact with operators in their commutants are given. Special attention is given to the closed subalgebra, not always the zero […]
