Current and Recent Colloquia
On November 28, 2012 from 1-2 pm in room HH-3017, Dr. Yuanlin Li (Brock University) will give an AAC Colloquium talk "Zero-divisor Graphs of Group Rings". This talk is joint with Dr. Farid Aliniaeifard (Brock University).
The abstract for this talk is available here.
On February 1, 2012, Dr. Eduardo Martinez-Pedroza (Memorial University) gave an AAC Colloquium Talk "Residual finiteness, subgroup separability and non-positively curved groups"
In this talk the notions of residual finiteness and subgroup separability were discussed in connection with non-positively curved groups. Research on non-positively curved groups is motivated by the study of lattices in real rank one semi-simple Lie groups and manifold topology. Open questions, motivation, and some of my work in the area were discussed.
On November 16, 2011 Dr. Sara Faridi (Dalhousie University) gave an AAC Colloqium talk "Combinatorics and Commutative Algebra"
That talk was about using graphs and hypergraphs to study questions in commutative algebra. Dr. Faridi discussed how problems in commutative algebra had led to the description of combinatorial structures that seemed to fit surprisingly well in the existed combinatorics literature. She also discussed open questions, and what the answers "should" look like.
On January 12, 2011 Professor Hugh Thomas of University of New Brunswick - Fredericton gave a Distingushed Colloquium Talk entitled "Garside structures for braid groups".
