Event title: Distinguished Lecture by David L. Donoho

Time: Wednesday, September 5, 2018 - 4:00pm to 5:00pm

Location: Suddath Seminar Room at the Petit Institute, 315 Ferst Drive, Rm. 1128

Organizers: Professors Jeff Wu, Santanu Dey, and Xiaoming Huo (ISyE)

Bio: David Leigh Donoho is a professor of statistics at Stanford University, where he is also the Anne T. and Robert M. Bass Professor in the Humanities and Sciences. His work includes the development of effective methods for the construction of low-dimensional representations for high-dimensional data problems (multiscale geometric analysis), developments of wavelets for denoising and compressed sensing.

In 1991, Donoho was named a MacArthur Fellow. He was elected a Fellow of the American Academy of Arts and Sciences in 1992. He was the winner of the COPSS Presidents' Award in 1994. In 2001, he won the John von Neumann Prize of the Society for Industrial and Applied Mathematics. In 2002, he was appointed to the Bass professorship. He was elected a SIAM Fellow and a foreign associate of the French Académie des sciences in 2009, and in the same year received an honorary doctorate from the University of Chicago. In 2010 he won the Norbert Wiener Prize in Applied Mathematics, given jointly by SIAM and the American Mathematical Society. He is also a member of the United States National Academy of Science. In 2012 he became a fellow of the American Mathematical Society. In 2013 he was awarded the Shaw Prize for Mathematics. In 2016, he was awarded an honorary degree at the University of Waterloo.

The conference will bring mathematicians together to discuss recent developments in smooth and symplectic low-dimensional topology and geometry. It is being held at the University of Texas, Austin, to celebrate the the 60th birthday of UT Austin's Jane and Roland Blumberg Centennial Professor in Mathematics Bob Gompf.

Organizers

The conference centers around the mathematics of Gompf. The organizers are Gompf's former Ph.D. students, including Georgia Tech School of Mathematics Professor John Etnyre.

  • John Etnyre, Georgia Institute of Technology
  • Laura Starkston, Stanford University
  • Jeremy Van Horn-Morris, University of Arkansas
  • Jonathan Williams, Binghamton University

Etnyre is leading a delegation of Georgia Tech students, postdoctoral fellows, and faculty.

Speakers

All the speakers are either collaborators of Gompf's or are working on problems related to Gompf's past and current work. 

  • Inanc Baykur (Umass Amherst)
  • Yasha Eliashberg (Stanford)
  • Shelly Harvey (Rice)
  • Rob Kirby (Berkeley)
  • Tian-Jun Li (Minnesota)

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.

Topics

  • Geometry of Hyperbolic Polynomials and Sums of Squares
  • Conic and Hyperbolic Programming
  • Interlacing Polynomials
  • Stable Polynomials in Combinatorics
  • Sums of Squares in Combinatorics and Optimization

Lecturers 

  • Daniel Plaumann (TU Dortmund)
  • Rainer Sinn (FU Berlin) 
  • Cynthia Vinzant (NC State) 
  • Greg Blekherman (Georgia Tech)
