At this meeting I gave an invited talk with the title

Lyapunov-Schmidt revisited

It was the first time since many many years that I gave a talk about my favorite topic from the start of my research career. I hope to find the time to write also a paper about this topic for the proceedings of the conference.

You can see here a slide show of the presentation.

The original presentation was made using the Keynote 3 software from Apple, which runs under Mac OS X 10.4 and above; the formulae were prepared using the LaTeXiT program.
