Lorenz Knots and Links
Joan Birman
2:00pm|S-101

The Lorenz differential equations, a system of non-linear ODE's in 3 space variables and time, have become well-known as the prototypical chaotic dynamical system with a `strange attractor'. A periodic orbit in the associated flow on $\mathbb R^3$...

Dynamics in Dimension 3: Geometry of Birkhoff Sections
Etienne Ghys
2:00pm|S-101

Birkhoff sections have been invented... by Poincaré in his work on celestial mechanics. Birkhoff made an extensive use of this concept in dynamical systems. Sometimes, one can find surfaces transverse to the trajectories of a vector field in a 3...

Lattices: from geometry to cryptography
4:00pm|S-101

Lattices are periodic arrangements of points in space that have attracted the attention of mathematicians for over two centuries. They have recently become an object of even greater interest due to their remarkable applications in cryptography. In...

From superconductors to Coulomb gases: crystallization questions
Sylvia Serfaty
2:00pm|Remote Access - see Zoom link below

The physicist Abrikosov predicted that in certain superconductors, one should observe triangular lattices of vortices, now called Abrikosov lattices.  When studying ground states of Coulomb gases, which is motivated by questions in approximation...

Pure Mathematics As Applied Physics
Tadashi Tokieda
2:00pm|Simonyi 101 and Remote Access

Humans tend to be better at physics than at mathematics.  After all, when an apple falls from a tree, there are more people who can catch it—they know physically how the apple moves—than people who can compute its trajectory from a differential...
