“ What is applied mathematics? An acceptable answer might be: mathematics in the service of matters that are exterior to mathematics itself. In that service, the question of logical proof or truth or finality is not really an issue; what matters is utility or significance, in some shape or form, to a sufficiently large group of people. With this criterion in mind, one can assert that Cardano's astrology constituted a non-negligible chapter in the history of applied mathematics. ”
by Philip J. Davis, in review of the book: Cardano's Cosmos: The Worlds and Works of a Renaissance Astrologer, by Anthony Grafton, Harvard University Press, 1999, 352 pages

Rigidity of Hamiltonian actions

By NTZung, on February 1st, 2011%

Finally (after several years of dragging our feet), my colleagues Eva Miranda and Philippe Monnier and I have just finished our paper on the rigidity of Hamiltonian actions of compact semisimple Lie groups on Poisson manifolds.

The rigidity phenomenon here is quite natural. It has been known for a long time that compact group . . . → Read More: Rigidity of Hamiltonian actions
