Aram Dermenjian, University of Quebec at Montreal, Facial weak order in hyperplane arrangements
We discuss the facial weak order, a poset structure that extends the poset of regions on a central hyperplane arrangement to the set of all faces of the arrangement which was first introduced on the braid arrangements by Krob, Latapy, Novelli, Phan and…
Find out moreJohn Perry, University of Southern Mississippi, The dynamic approach to Gröbner basis computation
Most algorithms to compute a Gröbner basis are “static”, inasmuch as they require as input both a set of polynomials and a term ordering, and preserve the term ordering throughout the computation. This talk presents ongoing work on “dynamic” Buchberger…

Join us tomorrow Wednesdays from 12:00-1:00 in the math graduate lounge for our weekly brown bag lunch. As a reminder all are welcomed including undergraduate students!
Find out moreOleksandr Misiats, Virginia Commonwealth University, Patterns around us: a calculus of variations prospective
Crumples in a sheet of paper, wrinkles on curtains, cracks in metallic alloys, and defects in superconductors are examples of patterns in materials. A thorough understanding of the underlying phenomenon behind the pattern formation provides a different prospective on the properties…

Geneva Collins Title : Automatic Geometric Theorem Proving: Sangaku From an Algebraic PerspectiveAbstract: During the Edo period (1603-1867 CE) Japan was almost completely closed off from the rest of the world and developed its own mathematical tradition called wasan. Part…
Find out moreYuanan Diao, Department of Mathematics and Statistics, UNC Charlotte, Braid Index Bounds Ropelength From Below
For an un-oriented link K, let L(K) be the ropelength of K. It is known that in general L(K) is at least of the order O((Cr(K))3/4), and at most of the order O(Cr(K) ln5 (Cr(K)) where Cr(K) is the minimum crossing number of…

Math Teachers’ Circle Workshop: Arvind Saibaba, Medical Imaging and other real life uses for mathematics
From ultrasound scanners used before birth to environmental sensors that monitor the pathways of harmful substances, imaging technologies play an important role in human lives. In this workshop, I will explain some of the mathematical ideas behind image reconstructions: how they work, what their…
Find out moreKrzysztof Putyra, University of Zurich, An equivalence between gl(2)-foams and Bar-Natan cobordisms
The original construction of the Khovanov homology of a link can be seen as a formal complex in the category of flat tangles and surfaces between them. There is a way to associate a chain map with a link cobordism, but only up…
