**Reidemeister torsion and its applications I**

It is known that we can classify the homeomorphism classes of 3-dimensional lens spaces by the Reidemeister torsion. We will see the Reidemeister torsion for lens spaces and its application to the classification of homeomorphism classes.

**Reidemeister torsion and its applications II**

We give an overview on the study of the Reidemeister torsion for 3-dimensional manifolds. Then we discuss the recent developments in the study of the asymptotic behavior of the Reidemeister torsion.

Majorana zero modes are fermion-like excitations that were originally proposed in particle physics by Ettore Majorana and are characterized as being their own anti-particle. In condensed matter systems Majorana zero modes occur as fractionalized excitations with topologically protected degeneracy associated with such excitations. For over a decade the only candidate systems for observing Majorana zero modes were the non-Abelian fractional quantum Hall state and chiral p-wave superconductors. In this talk, I will discuss a recent set of proposals for realizing Majorana zero modes in a large class of spin-orbit coupled, time-reversal symmetry broken superconducting systems. The simplicity of this class of systems has resulted in several experimental attempts, which have successfully observed preliminary evidence for the Majorana zero modes in the form of zero-bias conductance peaks and the fractional Josephson effect. Following this I will discuss future possibilities in terms of modifications to the experiments to help confirm the presence of Majorana zero modes through more dramatic signatures.

The Actuarial Student Association (ASA) will host an Actuarial Career Day Event with Willis Towers Watson, an actuarial consulting firm. The event will take place on Friday, September 30, 2016, from 12:00 pm to 1:30 pm in SSB 3.107 (Career Center Seminar Room).

Besides Actuarial Science, the following STEM majors are invited: Math, Statistics, Economics and Finance. Lunch will be served. Bring your resume and be ready to talk to the employer about your actuarial studies at UT Dallas and your future career plans.

We look forward to seeing you at this event!

Dr. Po-Shen Loh

Associate Professor of Mathematics, Carnegie Mellon University

Do you enjoy interesting problems? Do you want to find out how to make the most of math competitions?

Professor Po-Shen Loh will address puzzles that don’t look mathematical, but ultimately are unlocked by mathematical insights.

Metroplex Math Circle is pleased to provide this opportunity for free to the public thanks to our sponsor, AwesomeMath Academy.

Prof. Po-Shen Loh is Coach and Leader of the USA International Mathematical Olympiad Team, and founder of expii.com. He is also Associate Professor of Mathematics at Carnegie Mellon University.

The Metroplex Math Circle (MMC) is an enrichment program designed to attract talented students to mathematics and to provide an accelerated avenue to develop students' mathematical and problem-solving skills.

The Director of MMC is Dr. Titu Andreescu, UTD’s mathematics education associate professor, former director of the AMC and former coach of the US International Math Olympiad team. Dr. Andreescu is also the author of multiple books on Olympiad and collegiate level problem solving.

The MMC brings middle and high school students together with professors, researchers, teachers, and other students who share their interest, providing a social context for students who enjoy math.
