Network Conditions for Positive Recurrence of Stochastically Modeled Reaction Networks and Mixing Jinsu Kim University of Wisconsin - Madison PhD Graduate Student “Reaction networks are graphical configurations that can be used to describe biological interaction networks. If the abundances of... Read More
Generalized Dunce Hats do not have the Double Collapsible Property Pete Sparks Marquette University Instructor “We show that no generalized dunce hat can be decomposed into two collapsible subpolyhedra whose intersection is also collapsible. This is related to the notion... Read More
Hierarchies of Non-Positively Curved Cube Complexes Teddy Einstein Cornell University PhD Student “A non-positively curved (NPC) cube complex is a combinatorial complex constructed by gluing Euclidean cubes along faces in a way that satisfies a combinatorial local non-positive curvature condition....

Obstructions to Riemmanian Smoothings of a Locally CAT(0) Manifold Bakul Sathaye Ohio State University PhD Student “In this talk I will discuss obstructions to Riemannian smoothings of a locally CAT(0) manifold. I will focus on obstructions in dimension = 4... Read More
Cube Complexes and their Growth Series Richard Scott Santa Clara University Professor “A cube complex Y is a geometric object constructed by gluing together Euclidean cubes along their faces. If G is the fundamental group of Y, then there is... Read More
Multilinear Integral Operators: Classic, Curved, and Discrete Dong Dong University of Illinois at Urbana-Champaign Graduate Student “Several important integral operators in harmonic analysis will be presented in an organized way. The fundamental question about these operators is the boundedness on... Read More
Mathematical Modelling of Protein Oscillations in Bacteria Peter Rashkov Institute of Mathematics and Informatics - Bulgarian Academy of Sciences Associate Professor “Pole-to-pole oscillations of protein concentrations are observed in connection with cell division or movement and mathematical models have been...

Multistationarity in Biochemical Reaction Networks Dr. Maya Mincheva Northern Illinois University Associate Professor “Multistationarity is defined as the existence of several positive equilibria of an ordinary differential equations model. Multistationarity is a required property of biological switches - reaction networks... Read More
Due to weather related issues, this seminar has been cancelled and rescheduled from April 16 to its current date– Wednesday, April 18 at 2:00PM. We apologize for any inconveniences. The Visual Boundary of Hyperbolic Free-By-Cyclic Groups Ms. Emily Stark Technion-Israel... Read More
Nonmanifold Manifolds! Steven Ferry Rutgers University Professor Emeritus of Mathematics “We describe the construction of a collection of compact "n-manifolds" modeled on spaces other than R^n. These spaces provide counterexamples to a well-known conjecture of Bing-Borsuk. Both results and open... Read More
