The Applied Algebra Seminar
A Monday afternoon research seminar

About the seminar (click here to see more)

The seminar is currently organized by Laura Colmenarejo and Nantel Bergeron.

During 2017-18, the seminar takes place from 15:00-16:00 in Ross Building room N638. If you come by bus, the route 196A, 196B takes you to campus from Downsview subway station. If you come by car, you can find the available parking lots here.
The seminar has been running since 1997. The topics of talks have typically been any mixture of algebra with any other field: combinatorics, geometry, topology, physics, etc. Further down this page you will find links to the seminar webpages for previous years. The audience usually consists of 6–12 people, including several graduate students and post-docs. For this reason, speakers are encouraged to devote a portion of their talk to the suggestion of open problems and the directions for research in their area. If you are interested in speaking at the seminar, contact Laura Colmenarejo or Nantel Bergeron.

Dates are listed in reverse-chronological order. Unless otherwise indicated, all talks will take place on Monday from 15:00-16:00 in N638 Ross Building (York University).

Preserver Problems and Quantum Information Science
Preserver problems concern the study of transformations on matrices or operators with special properties. In this talk, we will describe the history and recent advance of the topic. In particular, we will mention some results and problems related to quantum information science. No quantum mechanics background is needed. Undergraduates who have taken an linear algebra course are welcomed to attend.

Structure of R-Polytopes on Relations
We introduce a class of {0,1} polytopes, assiciated to relations on a finite set, called R-polytopes. The R-polytopes generalize a number of classic polytopes including non-attacking rook placement polytopes and Stanley's chain polytopes. We have a general theorem that describes their 1-skeleton. The R-polytopes also appear in graph theory, finding their facets is central in vertex packing problem. We will discuss and give description of some of the facets. This is joint work with Aliniaeifard, Benedetti, Bergeron & Saliola.
