02/16/2019 Conference Oregon Number Theory Days Conference Our plenary speaker this year is John Voight from Dartmouth: https://math.dartmouth.edu/~jvoight/ John is an international leader in number theory, including areas such as quaternion algebras and computational number theory. He is also known for being a particularly outstanding expositor. I...
02/15/2019 Mathematical Biology Seminar Social behavior in bacteria
02/15/2019 Applied Mathematics and Computation Seminar Approximation of scalar conservation law with hysteresis. Part I. This is the first talk on the joint work with Ralph Showalter. This talk will focus on the modeling and computational aspects, with a surprising connection to diophantine approximations. Hysteresis is the dependence of a function not just on the present argument, but also on its history. In...
02/14/2019 Mathematics Education Seminar Discussion of "Constructivist, Emergent, and Sociocultural Perspectives in the Context of Developmental Research" by Paul Cobb and Erna Yackel
02/13/2019 Seminar The Directed Reading Program This is a talk in the graduate seminar MTH 607: Building Inclusive, Equitable, Respectful and Welcoming Mathematical Communities. In R1 institutions many undergraduates are left out of the experience of a research institution, and barely interact with tenure track faculty or graduate students. REU...
02/12/2019 Number Theory Seminar Quantum modular forms and singular combinatorial series Understanding the relationship between mock modular forms and quantum modular forms is a problem of current interest. Both mock and quantum modular forms exhibit modular-like transformation properties under suitable subgroups of the modular group, up to nontrivial error terms; however, their...
02/11/2019 Department Colloquium Liquid Crystals and Living Systems In order to further develop fundamental science and technologies of the future, it is pivotal to learn how to design, produce, and control the structure, properties, and dynamic behavior of soft materials within a broad range of spatial length scales, from the nanometer scale to macroscale. The...
02/11/2019 Applied Mathematics and Computation Seminar (Joint Analysis-AMC Seminar) Analysis of Liquid Crystal Flow (This is a joint Analysis -AMC Seminar). Since the mid-1990’s, a great deal of effort by the research community on partial differential equations has been devoted to the mathematical study of the Ericksen-Leslie equations of liquid crystal flow. Formulated as balance laws of linear and angular...
02/11/2019 Analysis Seminar (Joint Analysis and AMC Seminar today) Please see the joint event with AMC seminar https://math.oregonstate.edu/amc_seminar
02/08/2019 Mathematical Biology Seminar Within-host processes to population-level disease dynamics: Foot-and-mouth disease in African buffalo. Extremely contagious pathogens are among the most important global public and animal health concerns, because of their high burden of morbidity and mortality, their violent outbreaks, and as potential threats to biosecurity. Understanding the conditions and mechanisms that allow for robust...
02/08/2019 Applied Mathematics and Computation Seminar No seminar today: please participate in AMC-related events on Jan 31, 2/4, 2/11
02/07/2019 Mathematics Education Seminar Discussion of some of Engestrom's writing on CHAT (Cultural-Historical Activity Theory)
02/06/2019 Seminar Implicit Bias This is a talk in the graduate seminar MTH 607: Building Inclusive, Equitable, Respectful and Welcoming Mathematical Communities. The term "implicit bias" is becoming more and more common in public discourse. What does it actually mean? How does it differ from other forms of bias, and how might it...
02/05/2019 Number Theory Seminar Galois Representations Associated to Elliptic Curves and Modular Forms
02/04/2019 Department Colloquium Modeling the Melt: What Math Tells Us About Disappearing Polar Sea Ice The precipitous loss of Arctic sea ice has outpaced expert predictions. We will explore how mathematical models of key sea ice processes are being developed to improve projections of the future of Earth's sea ice packs and the polar ecosystems they support. Our models are inspired by theories of...
02/04/2019 Analysis Seminar Stability of diffusively coupled linear systems with an invariant cone - Part III This talk concerns a question that frequently occurs in various applications: Is any diffusive coupling of stable linear systems, also stable? Although it has been known for a long time that this is not the case, we shall identify a reasonably diverse class of systems for which it is true. In this...
02/01/2019 Mathematical Biology Seminar Loss of pollinator functional diversity in regenerating tropical forests reduces plant genetic diversity Forest regeneration can mitigate the negative effects of forest loss on species diversity, but less is known about how secondary and primary forests might differ in their ability to maintain genetic diversity. We quantified variation in genetic diversity of a hummingbird-pollinated, understory herb...
02/01/2019 Applied Mathematics and Computation Seminar Examining Curing Efficiency and Drying of Concrete Containing Superabsorbent Polymers using Neutron Radiography Many state highway agencies use prescriptive specifications for the curing of concrete bridge decks, pavements, flatwork, or structural elements. For example, concrete pavements are frequently specified to have a curing compound applied shortly after placement and bridge decks typically require...
01/31/2019 Applied Mathematics and Computation Seminar SIAM PNW seminar: From Causal Inference to Gene Regulation This seminar is the next in SIAM PNW Distinguished Online Seminar series. The seminar can be viewed online by the link to be provided below. A recent break-through in genomics makes it possible to perform perturbation experiments at a very large scale. The availability of such data motivates the...
