  1. 78. Poisson Geometry  of Difference Lax Operators  and Difference Galois Theory
    Prof. Michel Semenov-Tian-Shansky
    12/11/2013, 14:00
    We discuss the lift of Poisson structures associated with auxiliary linear problems for the differential and difference Lax equations to the space of wave functions. Due to a peculiar symmetry breaking, the corresponding differential and difference Galois groups become Poisson Lie Groups. Relations with the q-deformation of the Virasoro algebra is also described.

  4. 32. Geometry of the nuclear shell model
    Prof. Pieter Van Isacker
    12/11/2013, 15:15
    The shell model has become one of the standard tools for the interpretation of nuclear properties. It exists in a variety of guises ranging from the ab initio version where all nucleons interact with each other, to more phenomenological versions with schematic interactions between nucleons in the valence shell. Shell-model calculations frequently are computationally intensive, requiring the...

  5. 87. Wigner and the groups in classifying elementary particles and nuclear states
    Prof. József Cseh
    12/11/2013, 16:00
    Wigner did a pioneer work in the application of group theory in physics [1]. He made especially great contributions to the particle and nuclear physics [2]. The essential role of the representations of the inhomogeneous Lorentz group in classifying the elementary particles [3] is well known: a particle (fundamental or composite) transforms according to an irreducible...
