The 2018 Meeting on Applied Algebraic Geometry (MAAG 2018) will be hosted by the School of Mathematics at Georgia Institute of Technology on April 7-8, 2018. 

MAAG is a regional gathering that attracts participants primarily from the Southeast of the United States. Previous meetings took place at Georgia Tech in 2015 and at Clemson University in 2016.

Organizers of MAAG 2018 have invited several speakers from outside the Southeastern U.S. and are open to "longer distance" participants as well. Some funding is available to participate (see registration form, priority is given to students).

The main event on Saturday, April 7, will be followed by an informal Numerical Algebraic Geometry day on Sunday, April 8, which all participants are encouraged to attend.

Registration is free until March 1. After March 1, 2018, registration is $40.

Algebraic geometers in Georgia and neighboring southern states gather at the Georgia Tech School of Mathematics on Feb. 23-25, 2018, to strengthen their growing community. The goal is to support early-career mathematicians, especially those from groups that are underrepresented in mathematics. The gathering – the 2018 Georgia Algebraic Geometry Symposium (GAGS) – will provide attendees opportunities to network and be exposed to cutting-edge developments in the field.

Classical algebraic geometry studies questions about solutions sets of polynomial equations. For example, what is the dimension of the solution space? What is its shape? Can we break up the solution space into simpler components? Modern algebraic geometry includes much more abstract objects. 

Algebraic geometry has connections to complex analysis, string theory, topology, number theory, and game theory. It has applications in statistics, robotics, phylogenetics, and geometric modeling.

The Georgia Tech School of Mathematics is home to several experts in algebraic geometry: faculty members Matthew Baker, Greg Blekherman, Anton Leykin, Joseph Rabinoff, Kirsten Wickelgren, and Josephine Yu; postdoctoral fellows Padmavathi Srinivasan and Philipp Jell; and senior academic professional Salvador Barone.

Baker is organizing 2018 GAGS, with assistance from Rabinoff and Josephine Yu. The College of Sciences is providing additional financial support.

The 2018 symposium in Georgia Tech is the culmination of a three-year National Science Foundation (NSF) grant (DMS-1529573) to Georgia Tech, University of Georgia (UGA), and Emory University to organize and host GAGS in rotation over three years. The symposium was held at Emory University in 2016 and at UGA in 2017.

The 2018 GAGS features the following invited speakers, including one from Germany:

  • Linda Chen (Swarthmore College)
  • June Huh (Institute for Advanced Study)
  • David Jensen (University of Kentucky)
  • Jesse Kass (University of South Carolina)
  • Lek-Heng Lim (University of Chicago)
  • Kristin Shaw (Technischen Universität Berlin)
  • Andrew Snowden (University of Michigan)
  • Padmavathi Srinivasan (Georgia Institute of Technology)

Students are encouraged to attend. Registration is free.

Edit: This workshop was also featured in this story from the College of Science.

Workshop on introduction to dynamical systems methods for mission design

This workshop is designed to provide an introduction to recent methods to design orbits for spacecraft which use less fuel by taking advantage of natural gravitational forces. The analysis of such missions requires a deep understanding of the structure of phase space.

The workshop is part of a SURP grant by JPL Graduate and undergraduate students are encouraged to attend.

Some information on the workshop is available at: http://people.math.gatech.edu/~rll6/JPL/jpl.html

The Tech Topology Conference brings together established and beginning researchers from around the country for a weekend of mathematics in Atlanta. Check back soon for more details. We are pleased to announce this year's speakers:

The 2017 conference features a session of five-minute lightning talks.

If you are interested in giving such a talk (on behalf of your work or someone else’s) please see the "Registration and Support" page.
Deadline for submitting proposals for Lightning Talks is October 31.

organizers: J. Etnyre, J. Hom, P. Lambert-Cole, J. Lanier, C. Leverson, D. Margalit, and B. Strenner

The "Quolloquium" series is a set of talks at the colloquium level intended to update the local mathematics community on the topics discussed at QMath13, an international conference that took place at Tech in October, 2016.   Qmath13 broadly covered the mathematical aspects of quantum mechanics, including such fields as models with randomness, quantum information, many-body theory, and models on graphs and similar structures, as well as an open-ended topic of current mathematical problems in theoretical physics.  It is taking place at approximately two-week intervals in Fall Semester, 2017 and may extend into Spring Semester, 2018.

Title: Isoperimetric inequalities for convex cones
Speaker: Lotfi Hermi Florida International University lhermi@gmail.com
We use the weighted isoperimetric inequality of J. Ratzkin for a wedge domain in higher dimensions to prove new isoperimetric inequalities for weighted Lp-norms of the fundamental eigenfunction of a bounded domain in a convex cone-generalizing earlier work of Chiti, Kohler-Jobin, and Payne-Rayner. We also introduce relative torsional rigidity for such domains and prove a new Saint-Venant-type isoperimetric inequality for convex cones. Finally, we prove new inequalities relating the fundamental eigenvalue to the relative torsional rigidity of such a wedge domain thereby generalizing our earlier work to this higher dimensional setting, and show how to obtain such inequalities using the Payne interpretation in Weinstein fractional space. (Joint work with A. Hasnaoui)


Series: Math Physics Seminar
Title: Semiclassical Spectral Estimates with Renainder Terms
Starting from the classical Berezin- and Li-Yau-bounds onthe eigenvalues of the Laplace operator with Dirichlet boundaryconditions I give a survey on various improvements of theseinequalities by remainder terms. Beside the Melas inequalitywe deal with modifications thereof for operators with and withoutmagnetic field and give bounds with (almost) classical remainders.Finally we extend these results to the Heisenberg sub-Laplacianand the Stark operator in domains.
