Nonexistence of smooth solutions for the general compressible Ericksen -- Leslie equations in three dimensions
We prove that the smooth solutions to the Cauchy problem for the compressible
general three-dimensional Ericksen--Leslie system modeling nematic liquid
crystal flow with conserved mass, linear momentum, and dissipating total
energy, generally lose classical smoothness within a finite time.Comment: 7 pages. arXiv admin note: text overlap with arXiv:1206.2850,

Invariant generators for generalized distributions
The existence of invariant generators for distributions satisfying a
compatibility condition with the symmetry algebra is proved
Banach Lie-Poisson spaces and reduction
The category of Banach Lie-Poisson spaces is introduced and studied. It is
shown that the category of W*-algebras can be considered as one of its
subcategories. Examples and applications of Banach Lie-Poisson spaces to
quantization and integration of Hamiltonian systems are given. The relationship
between classical and quantum reduction is discussed.Comment: 58 pages, to apear in Comm.Math.Phy
