Автор: Polterovich L.
Аннотация:
Provides an essentially self-contained introduction to developments in the geometry of the group of sympletic diffeomorphisms. Features recent results on diameter, geodesics, and growth of one-parameter subgroups in Hofer's geometry, and applications to dynamics and ergodic theory. For researchers and graduate students. Softcover.
