User talk:Henri poincare

Welcome
Hello. I am impressed that somebody who died almost a century ago is still keeping track of recent developments in differential geometry :) Seriously though, welcome to Wikipedia and thank you for your contribution to Simon Donaldson. I hope you will continue to contribute to the encyclopaedia; people with specialized knowledge are essential. If you have any questions, please feel free to ask me on User talk:Jitse Niesen.
