Distinguished Visiting Professor Talk: Il Bong Jung 2/28 @ 4 pm in Olin 372

Title:  Quasinormality and weak quasinormality of operators   Abstract:  There are two notions to define the quasinormality of unbounded operators by Kaufman and Stochel-Szafraniec respectively. Our results show that Kaufman’s definition of an unbounded quasinormal operator coincides with that given by Stochel-Szafraniec. In this talk we discuss various characterizations of unbounded quasinormal operators. Examples demonstrating the sharpness of our results are constructed. An absolute continuity approach to quasinormality which relates the operator in question to the spectral measure of its modulus is developed. This approach establishes a new definition to be called weakly quasinormal operators. Some characterizations concerning to the […]

Distinguished Visiting Professor Talk: Ralf Schmidt 1/31 @ 4 pm in Olin 372

Title: What is Number Theory? Abstract: In its original meaning, Number Theory is concerned with the properties of the “natural” numbers 1, 2, 3, … In this talk we will attempt to explain how the consequent study of “elementary” properties of numbers leads naturally to the theory of automorphic forms and the vast web of conjectures known as the “Langlands program”.

DVP Talk: Amanda Folsom, 4/19 @ 4

Title:  Mock and quantum modular forms Abstract:  Mock modular forms were first formally defined in the literature by Zagier in 2007, though their roots trace back to the mock theta functions, curious power series described by Ramanujan in his last letter to Hardy in 1920. As the overarching theory of harmonic Maass forms has progressed over the last 15 years, we have seen applications of mock modular forms in number theory, combinatorics, representation theory, and more. Zagier also defined quantum modular forms in 2010, which like mock modular forms feign modularity in some way, but unlike mock modular forms are only […]

Student Talk Series: Matt Mizuhara ’12, March 24th @ 12 noon in Olin 268

Title: Mathematical biology under the microscope:  A study of cell motility Abstract: Although physics and chemistry have long relied on mathematics as a descriptive and exploratory tool, biological systems were historically seen as too complex to be understood theoretically. However, advances in mathematics and computational capabilities now allow for the quantification of biological problems in a field called mathematical biology. In this talk I will introduce a modern topic of mathematical biology: crawling cell motility. Cell motion plays a central role in wound healing and the immune response, e.g., to fight foreign bodies. We will present a partial differential equation model for […]

Student Talk Series: Mark Meyer, January 28th @ 12 noon in Olin 268

Title:  I’m all about that Bayes, ’bout that Bayes. Abstract:  A September 2014 New York Times article titled “The Odds, Continually Updated” discusses the growing popularity of Bayesian statistics both within and outside of the statistical community. This expansion is due in part to the growth of computing power over the last decade and a half. So what is Bayesian statistics? The title of the article, and indeed the article itself, suggest that Bayesian statistics uses, even requires, prior information to inform the analysis. But this is only a small aspect of the Bayesian approach. We can use Bayesian statistics to […]

DVP Talk: Sam Ventura, 12/7 @ 4 pm in Olin 264

Title:  Classification and Clustering for Record Linkage in Large Datasets Abstract: Record linkage, or the process of linking records corresponding to unique entities within and/or across data sources, is an increasingly important problem in today’s data-rich world.  Due to issues like typographical errors, name variation, and repetition of common names, linking records of unique entities within and across large data sources can be a difficult task, in terms of both accuracy and computational feasibility.  We frame record linkage as a clustering problem, where the objects to be clustered are the records in the data source(s), and the clusters are the unique […]

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 last year 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 […]
