[CV: Prof. Oded Margalit, PhD in Computer Science from Tel-Aviv University under the

supervision of Prof. Zvi Galil has worked at IBM's Haifa research lab on

machine learning, constraint satisfaction, verification and more. Currently he is the CTO

of the IBM Cyber security center of excellence at Ben Gurion University

of the Negev. Oded participates in organising several computer science

competitions (like the international IEEEXtreme and the national CodeGuru). He loves riddles and authors the monthly

challenge corner of IBM research: "Ponder-This".]

IBM
research runs a mathematical challenge site. Every month a new
challenge is posted; as well as a solution for the previous month's
riddle. Prof. Oded Margalit
is the puzzlemaster, for the last decade.
In the talk, he will survey some of the riddles over the years, and tell some anecdotes about the challenges and the solvers.
For example:
A 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 Intensive Care Unit and other stories; Finding a natural number n such that round ((1+2 cos(20))^n) is divisible by 10^9; We'll leave you with a still open question about Permutation-firing cannon...
Don't worry - no high math knowledge is assumed.

This is an Atlanta Science Festival performance in which mathematicians team up with dancers to give an artistic interpretation to the public of some mathematicians and some mathematical concepts. This year's show will have an emphasis on graph theory. There will be two performances at Drew Charter School in East Atlanta. For tickets go to https://www.freshtix.com/events/mathematics-in-motion---4pm-showing or https://www.freshtix.com/events/mathematics-in-motion---7pm-showing .

Degeneracy loci of morphisms between vector bundles have been used in a wide range of situations, including classical approaches to the Brill--Noether theory of special divisors on curves. I will describe recent developments in Schubert calculus, including K-theoretic formulas for degeneracy loci and their applications to K-classes of Brill--Noether loci. These recover the formulas of Eisenbud--Harris, Pirola, and Chan--López--Pflueger--Teixidor for Brill--Noether curves. This is joint work with Dave Anderson and Nicola Tarasca.

This is a workshop designed to provide an introduction to the use of
modern tools from Dynamical Systems in the design of space exploration
missions. More details and a detailed schedule is found in http://people.math.gatech.edu/~rll6/JPL/jpl.html

This is a preliminary talk for the Workshop "Introduction to Dynamical Systems Methods for Mission Design" that will take place Jan 16-19 in the school of Mathematics. In this talk, we will present the basics of Hamiltonian dynamics and why it is useful. It ishoped that it will be accesible for people with background in undergraduate differential equations who want to participate in the workshop.
