The Lax pair for C_2-type Ruijsenaars-Schneider model
We study the C_2 Ruijsenaars-Schneider(RS) model with interaction potential
of trigonometric type. The Lax pairs for the model with and without spectral
parameter are constructed. Also given are the involutive Hamiltonians for the
system. Taking nonrelativistic limit, we obtain the Lax pair of C_2
Calogero-Moser model.Comment: LaTeX2e, 10 pages, some misprints corrected and sections rearrange
Bosonization of quantum sine-Gordon field with a boundary
Boundary operators and boundary ground states in sine-Gordon model with a
fixed boundary condition are studied using bosonization and q-deformed
oscillators.We also obtain the form-factors of this model.Comment: Latex 25page
