[hep-th] seminar grupe za cestice i gravitaciju

[Branislav Cvetkovic]

Postovane kolege,

u petak 24.05. u 11 h na Institutu za fiziku,u sali 300, dr Nenad 
Manojlovic sa Univerziteta u Lisabonu
ce odrzati seminar pod naslovom "Jordanian deformation of the open 
sl(2) Gaudin model".

                                                                         
     Pozdrav Branislav


Abstract: We derive the deformed sl(2) Gaudin model with integrable
boundaries. Starting from the Jordanian deformation of the 
SL(2)-invariant
Yang R-matrix and generic solutions of the associated reflection 
equation
and the dual reflection equation, the corresponding inhomogeneous 
spin-1/2
XXX chain is obtained. The quasi-classical expansion of the transfer 
matrix
yields the deformed sl(2) Gaudin Hamiltonians with boundary terms.
