Title:
The work of Cheng and of Kaloshin and Zhang on Arnold diffusion for two and a half degrees of freedom.

Abstract:

More than a decade ago, I announced a proof of results on Arnold diffusion for two and a half degrees of freedom. I spent more than a decade writing a proof and never finished it.
Now two proofs of results similar to the ones I announced have appeared, one by Chong-Qing Cheng and the other by Kaloshin and Zhang. Both involve great simplifications and improvements.
I will attempt to describe the simplifications and improvements of these authors.

Colloquium coordinators are Prof.dr. A.C.D. van Enter (e-mail : A.C.D.van.Enter@rug.nl) and Dr. A.V. Kiselev (e-mail: a.v.kiselev rug.nl )
