Monday, 4/1

DOCTORAL DEFENSE
TITLE: Rejection Enhanced Off-Lattice Kinetic Monte Carlo
SPEAKER: Hamza Ruzayqat, University of Tennessee
TIME: 1:30 PM
ROOM: Ayres 405
His committee consists of Professors: Schulze (Chair), Karakashian, Wise, and Xu (MSE).

DOCTORAL DEFENSE
TITLE: Leptospirosis models: Vaccination of cattle and early detection in humans
SPEAKER: Ibrahim Aslan, University of Tennessee
TIME: 3:30 PM
ROOM: Ayres 123
His committee consists of Professors:  Lenhart (chair), Alexiades, Day and Eda (For., Wildlife, & Fish.).

DOCTORAL DEFENSE
TITLE: Coarse Proximity, Proximity at Infinity, and Coarse Structures
SPEAKER: Pawel Grzegrzolka, University of Tennessee
TIME: 3:35 PM
ROOM: Ayres 308H
His committee consists of Professors:  Dydak (chair), Brodskiy, Thistlethwaite, and Berry (EECS).


GEOMETRIC ANALYSIS READING SEMINAR
TITLE: Perelman’s monotonicity and kappa-noncollapsing
SPEAKER: Ryan Unger, University of Tennessee
TIME: 3:35 PM-5:30 PM
ROOM: Ayres 113
We will derive Perelman’s monotonicity formula for the graviton-dilaton action + Boltzmann entropy under Ricci flow. A consequence of this is kappa-noncollapsing for closed manifolds, which guarantees the existence of tangent flows.

Tuesday, 4/2

SIAM STUDENT CHAPTER TALK
TITLE: Finding Certainty in Randomness: My Journey with Mathematics
SPEAKER: Tanya Moore, Goodwill of San Francisco, San Mateo, and Marin Counties
TIME: 2:10 PM-3:10 PM
ROOM: Ayres 405
I love finding patterns. But, for a long time I couldn’t find them in my own life. Growing up life events felt random, chaotic even. Discovering mathematics in college gave me a way of bringing order and new possibility into my life. Professionally, it laid a foundation for me to tackle challenging social problems in health, education, and workforce development.  Math inspired me to fully engage life. This talk will explore why even the seemingly random steps in one’s academic and professional journey have magnitude and direction.

Tanya’s bio: Prior to joining Goodwill, Tanya’s professional career in local government and higher education focused on leading multi-agency collective impact initiatives focused on reducing health and education inequities and supporting college to career pathways.  After earning a Bachelor's degree in Mathematics from Spelman College she received doctorate training in the field of Biostatistics at the University of California, Berkeley and remains passionate in her support of women in STEM careers. Tanya is one of the co-founders of the Infinite Possibilities Conference, a conference designed to support, promote and encourage underrepresented minority women in mathematics. She has been featured in Essence Magazine, Black Enterprise and O, The Oprah Magazine and was recognized as one of the “STEM Woman of the Year” by California State Assembly member Nancy Skinner in April 2014.

Wednesday, 4/3

ANALYSIS SEMINAR
TITLE: Fair Peano Curves, part 2
SPEAKER: Joan Lind, University of Tennessee
TIME: 2:30 PM-3:20 PM
ROOM: Ayres 113
Given a spanning tree of a rectangular grid in some domain, one can create the so-called peano curve that winds around tree.  Thus the uniform spanning tree (UST), which is the random family of spanning trees that gives equal weight to each possible spanning tree, gives rise to a random family of peano curves.  Lawler, Schramm, and Werner showed that the scaling limit of these curves is SLE(8).  We will consider the notion of fair trees, which will lead to a different probability measure on spanning trees, and we will ask about the scaling limit of the corresponding fair peano curves.  This is joint work with Nathan Albin and Pietro Poggi-Corradini.

COMPUTATIONAL and APPLIED MATHEMATICS (CAM) SEMINAR
TITLE: Numerical Approximation of the Stochastic Cahn-Hilliard Equation Near the Sharp Interface Limit
SPEAKER: Andreas Prohl, Universität Tübingen
TIME: 3:35 PM-4:25 PM
ROOM: Ayres 113
In this talk I shall discuss a stable time discretization of the stochastic Cahn-Hilliard equation with an additive noise term $\varepsilon^{\gamma}\dot{W}$, where $\gamma >0$, and $\varepsilon>0$ is the interfacial width parameter. For sufficiently small noise (i.e., for $\gamma$ sufficiently large) and sufficiently small time-steps $k\leq k_0(\gamma)$, I shall present arguments which lead to strong error estimates where the parameter $\varepsilon$ only enters polynomially without using Gronwell’s lemma. This is joint work with D. Antonopoulou (Chester, UK), L. Banas (Bielefeld, Germany), and R. Nuernberg (London, UK).

Friday, 4/5

MATH BIOLOGY SEMINAR
SPEAKERS: Mahir Demir, Logan Perry, & Tyler Poppenwimer, University of Tennessee
TIME: 11:15 AM-12:05 PM
ROOM: Ayres 401
In this week's Math Biology seminar, Mahir Demir, Logan Perry, and Tyler Poppenwimer will begin presenting the paper "Efficacy of Infection Control Interventions in Reducing the Spread of Multidrug-resistant organisms in the Hospital Setting" by Mary Ann Horn, PhD, Case Western Reserve University.  (published in Plos One, 2012, vol. 7, no. 2).  The discussion of this paper will continue into the next week's seminar (on 4/12), followed on Monday, April 15th by a special seminar in which Dr. Horn will discuss the work with us in person!  Dr. Horn will also be giving a NIMBioS seminar on Tues. 4/16 - be sure to watch for announcements about it. If you are interested in being added to the Math Biology Seminar 'BaseCamp' site to receive notices and seminar materials directly, please contact Judy Day at judyday@utk.edu.  

GRADUATE STUDENT PROFESSIONAL DEVELOPMENT EVENT
TITLE: Industry Panel
PANELISTS: Greg Clark (Software Engineer at Google)
Nate Pollesch (Postdoctoral Mathematician at EPA)
Kelly Rooker (Senior Data Scientist I at Johns Hopkins Applied Physics Laboratory)
Kirill Yakovlev (Senior Vice President & Director of Data Science at Fifth Third Bank)
TIME: 3:35 PM-4:35 PM
ROOM: Ayres 405
Former UT math students with industry jobs will share information about their career paths and their advice for current grad students.
