TOPOLOGY/ GEOMETRY SEMINAR
TITLE: PROXIMITY INDUCTIVE DIMENSION AND BROUWER DIMENSION AGREE ON COMPACT HAUSDORFF SPACES
SPEAKER: Jeremy Siegert, University of Tennessee
TIME: 3:35 PM-4:25 PM
ROOM: Ayres 406
In this talk we show that the proximity inductive dimension defined by Isbell agrees with the Brouwer dimension originally described by Brouwer on the class of compact Hausdorff spaces. Consequently, Fedorchuk’s example of a compact Hausdorff space whose Brouwer dimension exceeds its Lebesgue covering dimension is an example of a space whose proximity inductive dimension exceeds its proximity dimension as defined by Smirnov.

GEOMETRIC ANALYSIS READING SEMINAR
TITLE: Qualitative classification of kappa-solutions
SPEAKER: Ryan Unger, University of Tennessee
TIME: 3:35 PM-5:30 PM
ROOM: Ayres 113
We'll introduce Qi Zhang's method of showing noncollapsing via the Sobolev inequality and start to classify kappa-solutions.

Wednesday, 4/10

COMPUTATIONAL and APPLIED MATHEMATICS (CAM) SEMINAR
TITLE: Aposteriori error control and adaptivity for Schrodinger equations
SPEAKER: Theodoros Katsaounis, University of Crete
TIME: 3:35 PM-4:25 PM
ROOM: Ayres 113
In this talk I will present some recent results on aposteriori error estimation for linear and nonlinear Schrodinger equations. We use finite element discretizations and the Crank Nicolson time stepping scheme. For the derivation of the estimates we use the reconstruction technique and linear and nonlinear stability arguments as in the continuous problem. Based on these aposteriori estimators we further design and analyse a time-space adaptive algorithm. Various numerical experiments verify and complement our theoretical results. This is a joint work with I. Kyza, Univ. of Dundee, UK. 

Thursday, 4/11

JR. COLLOQUIUM
TITLE: Geometric Constraints Everywhere
SPEAKER: Meera Sitharam, University of Florida
TIME: 3:40 PM-4:35 PM
ROOM: Ayres 405
The talk will tour 3 modeling scenarios:  supramolecular self-assemblies (such as viruses), sticky-sphere clusters, and material microstructure (composite, or designed for 3D printing).

Happily, as this talk will argue, much of the theory of geometric constraints, combinatorial rigidity and configuration spaces - already heavily utilized in macroscale modeling -  is well-suited to the micro and nanoscale.

Friday, 4/12

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 continue 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) and colleagues.  (published in Plos One, 2012, vol. 7, no. 2).  The following Monday, April 15th will be a special Math Biology 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 @ 12:40pm in Claxton 206 - 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.  

COLLOQUIUM
TITLE: Macromolecules and Materials: Wonderland through a Geometric Constraints Looking Glass
SPEAKER: Meera Sitharam, University of Florida
TIME: 3:35 PM-4:35 PM
ROOM: Ayres 405
The talk will tour 3 modeling scenarios:  macromolecular self-assemblies (such as viruses), sticky-sphere clusters, and material microstructure (composite, or designed for 3D printing).

The goal of the talk is to illustrate how theorems, core algorithms -  the theory of geometric constraints, combinatorial rigidity and configuration spaces - are crucial for efficient modeling, analysis, mechanistic understanding and design. We consider of various material properties and phenomena from distribution of density/stress/strain, fracture and cryptomorphic physical phenomena, to configurational entropy and kinetics.
