### Students Elected to Phi Beta Kappa

**ΦBK**(Phi Beta Kappa) is a national academic honor society, founded in 1776, and currently having chapters at 280 American colleges and universities. According to its web site, "Phi Beta Kappa celebrates and advocates excellence in the liberal arts and sciences. Its campus chapters invite for induction the most outstanding arts and sciences students at America's leading colleges and universities."

In 2011, the following mathematics students were selected by Zeta of New York, the HWS chapter of ΦΒΚ, for membership:

**Yaoxin Liu (H'12)****Jessica Tarantino (WS'12)****Sarah Tarantino (WS'12)**

It is noteworthy that all three students were elected to membership as Juniors, which is considered a singular honor.

### Sigma Xi Nominees

*Sigma Xi*(www.sigmaxi.org) is an international scientific research society, founded in 1886 to "honor excellence in scientific investigation and encourage a sense of companionship and cooperation among researchers in all fields of science and engineering."

Each year, students who have done research in mathematics or
computer science and who are in their last year at the Colleges are
nominated by the Department of Mathematics and Computer Science
for student membership in *Sigma Xi*.

For 2011, the nominees are:

**Max Beckett (H'11)****Reynaldo Kelly (H'11)****Yixiao (Selena) Sha (WS'12)**

(Selena, who is in the 3-2 Engineering program, was nominated as a Junior because she will be moving on to Columbia University next Fall to complete the engineering program.)

### Math Awareness Month

The web site www.mathaware.org has information about the annual celebration of Math Awareness Month in April 2011.

"Unraveling Complex Systems" is theme for Mathematics Awareness Month, April 2011, as per a joint announcement from the American Mathematical Society, the American Statistical Association, the Mathematical Association of America, and the Society for Industrial and Applied Mathematics. Mathematics Awareness Month is sponsored by the Joint Policy Board for Mathematics (JPBM).

How do epidemics spread, birds flock, and stock markets operate?

Many of these answers fall within the realm of mathematics.

From natural entities such as living cells, insect colonies and whole ecosystems to man-made inventions like power grids, transportation networks and the World Wide Web, we see complex systems everywhere. Deciphering the mathematics behind such systems can unravel well-structured networks and discernible patterns in natural and artificial structures. That is the idea behind Mathematics Awareness Month.

Understanding these complex systems can not only help us manage and improve the reliability of such critical infrastructures of everyday life, but can also allow us to interpret, enhance and better interact with natural systems. Mathematical models can delineate interactions among components of these systems, analyze their spontaneous and emergent behaviors, and thus help prevent undesirable developments while enhancing desirable traits during their adaptation and evolution.

### Article Published

Trevor Gionet (Hobart College '12) and Yixiao Sha (William Smith College '12) worked on a summer research project in 2010 with Professor Erika King. The goal of the project was to find a more efficient way of proving a theorem characterizing 4-regular, claw-free, well-dominated graphs, which was originally proved by Prof. King using roughly 350 pages. However, during their first week of research, Yixiao and Trevor discovered a graph that was omitted from a characterization by Michael D. Plummer originally used to prove Prof. King's theorem. Thus their research was redirected to revise Plummer's characterization.

Trevor and Yixiao were able to complete Plummer's characterization, revise a result in a paper that used that characterization, and prove a case of Prof. King's theorem. They wrote an article with Prof. King entitled "A revision and extension of results on 4-regular, 4-connected, claw-free graphs", that includes their results. The paper was recently accepted into the journal Discrete Applied Mathematics.
