Current Academic Year Seminars

BLOCK 2, 2015 - September/October

Friday, October 2nd at NOON 
TSC 122 - Kresge Lecture Hall
Pizza will be provided!

Speaker: Benjamin Ylvisaker
Title: "Google, The NSA and The Supreme Leader are Listening!"  

Rated: PG

Abstract: There is an enormous amount of private data sent and stored insecurely over the Internet. Powerful governmental, corporate and/or criminal organizations are actively collecting and exploiting this data. This talk will introduce a broad range of concepts in
information security and privacy. In particular we will discuss new ideas related to storing data securely in public cloud storage services.

All majors must write up four talks in order to graduate.  Talk write ups should be submitted through Canvas.  If you wish to be added to the Canvas page, please contact one of the paraprofs.  


Friday, September 4th at 2:30pm in TSC 229
Speaker: Darren Funk-Neubauer
Title: "Bidiagonal Pairs and Bidiagonal Triples."

Rated: PG-13 with R rated sections

Abstract: Roughly speaking, a bidiagonal pair is a pair of diagonalizable linear transformations on a finite-dimensional vector space, each of which acts in a bidiagonal fashion on the eigenspaces of the other. A classification of bidiagonal pairs will be presented. Then I will describe how to construct all bidiagonal pairs using representations of the Lie algebra sl2 and the quantum group Uq (sl2) . Next, I will explain how to extend the definition of bidiagonal pair to a triple of linear transformations, thus defining a bidiagonal triple. I will discuss in what sense a given bidiagonal pair determines a bidiagonal triple. Lastly, I will describe the classification of bidiagonal triples.


BLOCK 1, 2015 - August/September

Departmental Research Overview and Ice Cream Social
Friday, September 4th at NOON
TSC 122 - Tutt Science Lecture Hall

Rated G

This general-audience talk will showcase the various research interests of the Department of Mathematics and Computer Science at Colorado College. Each faculty member will provide a brief description of their scholarly pursuits. Pizza will be provided!
Faculty speakers will include
• Marlow Anderson - Wild Automorphisms of the Complex Plane, History of Mathematics
• David Brown - Mathematical Biology
• Andrea Bruder - Differential Equations
• Rodney James - Tropical Geometry
• Steven Janke – Computational Complexity
