[Topology.beta] Announcement: Talk by Valerio Assenza

[Benedetti, G. (Gabriele)]

Dear all,

A quick reminder that today at 3:30pm in the Mathlab, the talk of Valerio Assenza will take place (title and abstract below).

Afterwards, at 5:30pm we go to the DeBoele bar for some drinks and from there we go to Market 33 for dinner at around 6:30pm.

Best,

Gabriele

Title:
Magnetic Curvature and Existence of Closed Magnetic Geodesic



Abstract:

A Magnetic System is the toy model for the motion of a charged particle moving on a Riemannian Manifold endowed with a magnetic field.
Solutions for such systems are called Magnetic Geodesic and preserve the Kinetic Energy. One of the most relevant investigative interest in the theory is to understand the existence and in case the topological nature of Closed Magnetic Geodesics (periodic solutions) in a given level of the energy. I will introduce the Magnetic Curvature, an object which encodes the geometrical properties coming from the Riemannian Curvature structure together with terms of perturbation due to the magnetic interaction. We will see how a positive curved Magnetic System carries a Contractible Closed Magnetic Geodesic for small energies.

Dear all,

The starting time of Valerio Assenza’s talk next Tuesday has been moved to 3:30pm (i.e. thirty minutes later than the original time) so that some more interested people can come.

Have a great day!

Gabriele
