The summer school is aimed at graduate students and recent Ph.D.'s. The goal is to introduce early-career researchers to the latest developments in the theory of hyperbolic polynomials, sums of squares and their applications in combinatorics and optimization. School of Mathematics Professor Greg Blekherman is the organizer. 

Hyperbolic and stable polynomials have seen several spectacular applications in combinatorics and optimization in recent years.

A hyperbolic polynomial in one variable is just a real polynomial with only real roots, while a hyperbolic polynomial in several variables can be seen as a familiy of such real-rooted polynomials in one variable. They appear in several different areas, and a beautiful geometric theory with many surprising features has evolved around their study. 

Nonnegative polynomials and sums of squares are classical subjects of real algebraic geometry, dating back to Hilbert's 17th problem. There are also rich connections to real analysis via duality and moment problems, as well as to polynomial and combinatorial optimization.

TA Awards Process

The Center for Teaching and Learning (CTL) is excited to celebrate the contributions to teaching excellence at Georgia Tech made by our graduate and undergraduate teaching assistants. The 2018 award process will officially open January 1, 2018. CTL asks that all schools/departments conduct an internal competition to produce one person in each of the following categories, where applicable: (1) Graduate Student Instructor of the Year; (2) Graduate Teaching Assistant of the Year; and (3) Undergraduate Teaching Assistant of the Year. Eligible candidates will have taught between Spring 2017 and Spring 2018. When we receive the names of the department winners, each will be invited to submit an application to participate in the campus-wide competition, which is overseen by CTL. All recipients of school/department awards will be honored and the campus-wide winners announced at the Spring 2018 TA and Future Faculty Awards Day ceremony.

Important Dates to Remember:

A Frontiers in Science Lecture by Lance Fortnow, Chair of the School of Computer Science

What is computer science? Ask Google or Alexa, and you'll get an answer like "the study of the principles and use of computers." That doesn't really capture the breadth of the field.

But how can you get an answer in a fraction of a second? Now that's computer science!

Lance Fortnow will explore

  • the ideas developed by computer scientists that transport your Google query to the cloud 
  • how the cloud keeps track of the massive amount of information needed to answer the question 
  • how algorithms and machine learning figure out what your question means and how best to respond 

All these take place in that six-tenths of a second from the time you make the query until answers magically appear, while keeping your information secure and private all the time. 

About the Speaker
Lance Fortnow is professor and chair of the School of Computer Science in the College of Computing at the Georgia Institute of Technology. His research focuses on computational complexity and its applications to economic theory.

Fortnow received his Ph.D. in Applied Mathematics at Massachusetts Institute of Technology in 1989, under the supervision of the theoretical computer scientist Michael Sipser. Before joining Georgia Tech in 2012, Fortnow was a professor at Northwestern University and the University of Chicago, a senior research scientist at the NEC Research Institute, and a one-year visitor at Centrum Wiskunde & Informatica (CWI; National Research Institute for Mathematics and Computer Science) and the University of Amsterdam, in the Netherlands. Since 2007, Fortnow has held an adjoint professorship at the Toyota Technological Institute, in Chicago.

Fortnow's research spans computational complexity and its applications, most recently to microeconomic theory. His work on interactive proof systems and time-space lower bounds for satisfiability have led to his election as a 2007 Association for Computing Machinery (ACM) Fellow. Fortnow was a National Science Foundation Presidential Faculty Fellow from 1992 to 1998 and a Fulbright Scholar to the Netherlands in 1996-97.

Among his many activities, Fortnow has served as the founding editor-in-chief of the ACM Transaction on Computation Theory, as chair of ACM Special Interest Group on Algorithms and Computation Theory (SIGACT), and as member of the Computing Research Association board of directors. He served as chair of the IEEE Conference on Computational Complexity from 2000 to 2006.

Fortnow originated and has coauthored the Computational Complexity weblog since 2002, the first major theoretical computer science blog. He has thousands of followers on Twitter

Fortnow's survey "The Status of the P versus NP Problem" is the most downloaded article of the journal Communications of the ACM. Fortnow has written the popular science book "The Golden Ticket: P, NP and the Search for the Impossible," which is loosely based on that article.

Book signing follows the lecture.

A School of Mathematics Seminar with IBM Research puzzlemaster Oded Margalit

IBM Research runs a mathematical challenge site, called "Ponder This." Every month the site posts a new  challenge and reveals the solution for the previous month's riddle. Oded Margalit has been the puzzlemaster since 2005.  He will survey some of the riddles over the years and tell some anecdotes about the challenges and the solvers, for example: 

  • PRL paper born from a riddle on random walks 
  • ITA-2014 paper on water hose model (using quantum entanglement to break location based encryption)
  • Games: 2048, Kakuro, Infinite chess game, the probability of a backgammon to end with a double Fisher Foul Chess and more 
  • Minimal hash function 
  • Combinatorial test design 
  • A solver from the intensive care unit and other stories 
  • Finding a natural number n such that round ((1+2 cos(20))^n) is divisible by 10^9

Don't worry! No high mathematics knowledge is assumed.

About the Speaker
Oded Margalit received his Ph.D. in Computer Science from Tel-Aviv University under the supervision of Zvi Galil, now the dean of the Georgia Tech College of Computing. 

Margalit has worked at IBM's Haifa research lab on machine learning and constraint satisfaction, verification, and more. He is the chief technology officer of the IBM Cyber Security Center of Excellence at Ben Gurion University of the Negev.

Oded participates in organising several computer science competitions, such as the international IEEEXtreme and the national CodeGuru. He loves riddles and is the author of "Ponder This," the monthly challenge corner of IBM Research.
