We organize lunches, seminars and teas.
- Inaugural Intersections seminar talk:
Date: February 21, 2019
Speaker: Melody Chan (Brown University)
Location: LOM 215, 4pm
Title: Tropical curves, graph complexes, and the cohomology of M_g
Abstract: The cohomology ring of the moduli space of curves of genus g is far
from being fully understood. For example, in the 1980s Harer-Zagier
showed that the Euler characteristic of M_g (up to sign) grows
super-exponentially with g-yet most of this cohomology is not
explicitly known. In joint work with Galatius and Payne, we identify a
new source of rational cohomology in M_g in degree 4g-6, with
dimension growing exponentially in g, disproving a vanishing
conjecture of Kontsevich.
The talk will be followed by an informal discussion on the issue of diversity in Mathematics.
- Intersections seminar talk:
Location: LOM 215, 4:15 pm
Date: April 10, 2019
Speaker: Gigliola Staffilani (MIT)
Title: How the study of complex wave phenomena inspires beautiful mathematics
Abstract: Waves are all around us: ocean waves, sound waves, rainbows…scientists have spent countless hours trying to understand them, to predict them and to harness from them the energy that they encapsulate. In this talk I will try to convey how the mathematical study of these physical phenomena have also created and inspired a whole set of new mathematical tools that are elegant, powerful and also incredibly beautiful in their abstract nature. These tools are now used to answer open problems in completely different setting, from number theory to probability, to symplectic geometry and more.
