ALGEBRA SEMINAR
TIME: 3:35 - 4:25 p.m.
ROOM: Ayres B004
SPEAKER: Mr. Vajira Manathunga
TITLE: Arithmetic progressions in a UFD
PROBABILITY SEMINAR
TIME: 3:35-4:25 p.m.
ROOM: Ayres 112
SPEAKER: Ms. Parisa Fatheddin
TITLE: Large and Moderate Deviations for Some Measure-Valued Processes. Part I
ABSTRACT: In this talk Moderate Deviations are considered for a class of stochastic partial differential equations (SPDEs). Since two important population models, super-Brownian Motion and Fleming-Viot Process, can be represented by SPDEs, then, as an application, Moderate Deviations are derived for these models as well. I will begin by characterizing Central Limit Theorem (Normal Deviations), Large and Moderate Deviations by looking at the difference between the calculated mean and the actual mean. The first talk will be a review on Large Deviations for the above SPDEs. The Moderate Deviations will be covered in the second talk.
Wednesday, September 12
MATH BIOLOGY SEMINAR
TIME: 10:10 - 11:00 a.m.
ROOM: Dabney 488
SPEAKER: Tom Ingersoll, NIMBioS postdoc
TITLE: Introduction to R and data
ANALYSIS SEMINAR
TIME: 3:35 - 4:30 p.m.
ROOM: Ayres 112
SPEAKER: Prof. Stefan Richter
TITLE: Does the Bergman shift have the transitive algebra property?
ABSTRACT: This will be the second of several talks by Professors Richter and Sundberg. We will discuss examples of unital operator algebras that contain the Bergman shift, are not dense, and have no "obvious" common invariant subspaces.
COMP/APPLIED MATH SEMINAR
TIME: 3:35-4:30 p.m.
ROOM: Ayres 110
SPEAKER: Ms. Amanda Diegel, Math Department, UTK
TITLE: Two Modified Cahn-Hilliard Equations and Some Applications Involving Moving Interfaces
Thursday, September 13
JUNIOR COLLOQUIUM
TIME: 3:35 - 4:30
ROOM: Ayres 405
SPEAKER: Professor Carla Cederbaum, Duke University
TITLE: From Newton to Einstein: a guided tour through space and time
ABSTRACT: The cosmos and its laws have fascinated people since the ancient times. Many scientists and philosophers have tried to describe and explain what they saw in the sky. And almost all of them have used mathematics to formulate their ideas and compute predictions for the future. Today, we
have made huge progress in understanding and predicting how planets, stars, and galaxies behave. But still, the mysteries of our universe are formulated and resolved in mathematical language and always with new mathematical methods and ideas.
In this lecture, you will hear about two of the most famous physicists of all times, Isaac Newton (1643-1727) and Albert Einstein (1879-1955), and about their theories of the universe. You will learn about common features and central differences in their viewpoints and in the mathematics they used to formulate their theories. In passing, you will also encounter the famous mathematician Carl Friedrich Gauss (1777-1855) and his beautiful ideas about curvature.
Pizza will be available at 3:15 in 401.
Friday, September 14
COLLOQUIUM
TIME: 3:35 - 4:30
ROOM: Ayres 405
SPEAKER: Professor Carla Cederbaum, Duke University
TITLE: The Geometry of Static Spacetimes in General Relativity
ABSTRACT: Einstein's General Relativity is a geometric theory of space, time, and gravitation. In some sense, it is the successor of Newton's famous theory of gravitation -- the theory Newton is said to have come up with when an apple fell onto his head. But although Einstein's theory is much better at predicting gravitational effects in our universe, Newton's theory is not at all outdated or even obsolete. In fact, many astrophysical measurements and simulations still heavily rely on Newtonian intuitions, calculations, and concepts. In the talk, I will explain how and to what extent this usage of Newtonian theory in astrophysics and related fields is motivated and mathematically justified. This will lead us to the notion of Newtonian limit. We will also see some examples for the behavior of relativistic quantities like mass and center of mass under this Newtonian limit.
