Monday, February 1st

GEOMETRY AND TOPOLOGY SEMINAR
TITLE: Introduction to Algebraic Geometry
SPEAKER: Mark Bly, UTK
TIME: 2:30pm – 3:20pm
ROOM: Ayres 113
This talk will focus on basics of algebraic geometry. The goal will be to deliver a general feel for the area through a description of its various features, strengths, and weaknesses, as well as its peculiarities and similarities as compared to other areas (especially geometry/topology). Emphasis will be on explanation and example rather than detailed proof.


Tuesday, February 2nd

STOCHASTICS
TITLE: Organizational Meeting
SPEAKER: Jan Rosinski, UTK
TIME: 2:10pm – 3:25pm
ROOM: Ayres 114


Wednesday, February 3rd

COMPUTATIONAL AND APPLIED MATHEMATICS SEMINAR
TITLE: Multiswitching and Volumetric Dose Penalizations for Optimal Control of PDE’s
SPEAKER: Richard Barnard, ORNL
TIME: 3:35pm – 4:35pm
ROOM: Ayres 114
This talk will discuss two novel optimal control problems governed by partial differential equations (PDEs). The first problem is one where a control signal has several different input channels, however only one should be active at any time; such a control is called a multiswitching control. The second involves a problem where the volume of the region where the state exceeds a given value should be minimized; this is in contrast to a standard pointwise box constraint and corresponds to a constraint on the state’s cumulative histogram. This problem involves a volumetric dose penalization, as it is motivated by a problem in radiotherapy. In each case, we will discuss convex-analysis techniques for solving these problems, as well as numerical implementations.


Thursday, February 4th

MATH ECOLOGY/ EVOLUTION SEMINAR
SPEAKER: Logan Perry
TIME: 10:00am – 11:00am
ROOM: Ayres 404
Chapter 3 of Bowles & Gintis book “Cooperative Species”

DIFFERENTIAL EQUATIONS SEMINAR
TITLE: Modeling an Invasive Species in a River and Using Optimal Control for Management
SPEAKER: Rebecca A Pettit, UTK
TIME: 2:10pm – 3:25pm
ROOM: Ayres 114
Many past models for river species have either focused on population dynamics or river dynamics. I will be discussing the origin of a model built to incorporate time-dependent river flow with population dynamics. I will then discuss how to find the optimal control for this model.

GRADUATE STUDENT SEMINAR
TITLE:
SPEAKER: Grace McClurkin and Josh Mike, UTK
TIME: 3:40pm – 4:30pm
ROOM: Ayres G004
We will describe how we are using Mathematica to supplement both the in-class and out-of-class experiences of students enrolled in a flipped format multivariable calculus course.  In particular, we will focus on the course design including notes, guided pre-class practice and structured group work.


Friday, February 5th

ANALYSIS SEMINAR
TITLE: Functions as quotients of multipliers, II
SPEAKER: Stefan Richter, UTK
TIME: 2:30pm - 3:20pm
ROOM: Ayres 121
It follows from a classical theorem of F. Riesz that every function in the Hardy space H^2 can be written as a quotient of two bounded analytic functions. I will discuss analogues of this result in spaces other than H^2.
