Georgia Institute of Technology College of Sciences

As part of Mathematics Awareness Month, some of the professors in the School of Mathematics participated in interviews that explored their research focus, highlights of their career, and their personal insights. The interviews became a series of Get to Know the Math Professor articles that were featured on the School of Math website last month. All together, sixteen articles were published, and links to all of the articles are listed below.

Through a series of research papers posted online in recent weeks, mathematicians have solved a problem about the pattern-matching card game, Set, that predates the game itself. The proof, whose simplicity has stunned mathematicians, is leading to advances in other combinatorics problems.

Three mathematicians in particular, Ernie Croot of the Georgia Institute of Technology (pictured to the right), Vsevolod Lev of the University of Haifa, Oranim, in Israel, and Péter Pál Pach of the Budapest University of Technology and Economics in Hungary, posted a paper online, on May 5, showing how to use a polynomial method to solve a closely related problem. In their work, the three researchers used Set attributes with four different options instead of three. For technical reasons, this problem is more tractable than the original Set problem. Not long after this, two mathematicians, Jordan Ellenberg, and Dion Gijswijt, each independently posted papers showing how to modify the argument to polish off the original cap set problem, and a joint paper combining their results. 

The work of Ernie Croot and his collaborators is continuing to make huge waves, with many interesting consequences now unfolding. Their work has already been applied to matrix multiplication, tri-colored sum-free sets, and the Erdös-Szemerédi sunflower conjecture, which concerns sets that overlap in a sunflower pattern. Their work was also featured in an article in Quanta Magazine, which gives a more detailed history of this recent breakthrough.

The Topology Students Workshop to be held during June 6-10, 2016 will feature research talks by leading mathematicians in geometry and topology, and will have hands-on training and panel discussions on professional development topics such as:

• Creating and delivering research presentations
• The grant writing process
• The publishing process
• Navigating the hiring process
• Writing teaching statements and research statements
• Working with Sage, Beamer, and Inkscape
• Creating a professional web page
• Careers in and out of academia
• Teaching effectively and efficiently
• Applying for jobs

Participants will also have the opportunity to give their own 20 minute lectures and have them critiqued in a constructive environment. The workshop is geared towards graduate students in the areas of geometry and topology.

Professors Matt Baker and Josephine Yu are organizers of the SIAM 2016 Minisymposium on Tropical Mathematics to be held at Georgia State University during June 6-10, 2016. Professor Joseph Rabinoff is one of the speakers.

Dr. Matt Baker is a featured speaker at the Benjamin Peirce Centennial Conference which will be held at Harvard University in June 2016.  This prestigious gathering of mathematicians includes Fields Medalists and other leading researchers.  It celebrates 100 years of the Benjamin Peirce Fellowship at Harvard.

Five faculty members in the College of Sciences are among the recent recipients of the early-career grants from the National Science Foundation (NSF). The highly competitive awards are from the NSF Faculty Early Career Development (CAREER) program; they provide five years of funding to junior faculty.

Of the five College of Sciences CAREER award recipients, four are assistant professors in the School of Mathematics. Their names and research interests are:

• Michael K. Damron - dynamical systems, probability, and statistics

• Esther Ezra - discrete geometry, combinatorics, probability, discrepancy theory, and approximation algorithms

• Jennifer C. Hom - low-dimensional topology, Heegaard Floer homology, knot theory, concordance, and Dehn surgery

• Kirsten G. Wickelgren - algebra, geometry, and topology

Amit R. Reddi, an assistant professor in the School of Chemistry and Biochemistry, is the fifth College of Sciences CAREER awardee. Reddi studies metalloproteins. His lab is interested in determining the cellular, molecular, and chemical mechanisms by which these proteins are activated in cells and their roles in cell metabolism and physiology. 

"I'm thrilled - but not at all surprised - by the recognition of accomplishment and promise by our early-career colleagues that these NSF CAREER awards signal. Their successes reflect the vigor they bring to their respective schools and to mathematics and the sciences at Georgia Tech," says College of Sciences Dean Paul M. Goldbart.

The CAREER awards are NSF's most prestigious grant to support junior faculty who exemplify the role of teacher-scholars. Through five years of sustained support, the award enables promising and talented researchers to build a foundation for a lifetime of leadership in integrating education and research.

During July 11-15, 2016 Georgia Tech will host Summer School on Real Algebraic Geometry and Optimization organized by Greg Blekherman and Rainer Sinn (Georgia Tech) and Mauricio Velasco (Universidad de los Andes). The summer school is aimed at graduate students and recent PhD's with the goal of introducing them to latest developments in the theory of nonnegative polynomials and sums of squares and applications. The topics for the school are:

• Geometry of Sums of Squares and Nonnegative Polynomials, recent connections with Classical Algebraic Geometry
• Applications of Sums of Squares Methods in Optimization and Engineering

Location: Skiles 006.

Dan Margalit, has been selected to receive the inaugural 2016 Leddy Family Faculty Fellowship.

The Leddy Family Faculty Fellowship is awarded to a tenure track faculty member in the College of Sciences. The award is made to further the goals of the College by supporting development of the research and training program and quality of instruction of a mid-career faculty member (loosely defined as a tenured Associate Professor, or one who is just before promotion to this rank, or just after promotion from this rank). This award is made possible through a generous gift to the College of Sciences from Jeff '78 (Physics) and Pam Leddy.

Michael Damron is the 2016 recipient of the LexisNexis Dean's Excellence Award in the College of Sciences. The award recognizes Damron's teaching and mentoring efforts, including placement of postdoctoral fellows, as well as his excellent research contributions. Earlier this year, Damron received a National Science Foundation Faculty Early Career Development (NSF CAREER) award.

LexisNexis is a provider of legal, government, business, and high-tech information and other services. "The purpose of this award is to recognize outstanding educators from among the untenured junior faculty at the assistant professor level," according to LexisNexis. "Award recipients are selected for extraordinary effectiveness in classroom teaching, educational innovations, inspiration transmitted to students, direct impact and involvement with students, and impact on the postgraduate success of students."

In 2014, Martin Short, was the recipient of the award in the College of Sciences.
