Integrability of the symmetry reduced bosonic dynamics and soliton generating transformations in the low energy heterotic string effective theory
G. A. Alekseev
Integrable structure of the symmetry reduced dynamics of massless bosonic sector of the heterotic string effective action is presented. For string background equations that govern…
A Lorentz invariant formulation of the Yang-Mills theory with gauge invariant ghost field Lagrangian
A. A. Slavnov
A new formulation of the Yang-Mills theory which allows a manifestly covariant gauge fixing accompanied by a gauge invariant ghost field interaction is proposed. The gauge conditio…
Iterative construction of representations and Lax matrix factorisation
S. Derkachov, D. Karakhanyan, R. Kirschner +1
The construction of a generic representation of or of the trigonomentric deformation of its enveloping algebra known as algebraic induction is conveniently formulated…
Correlation functions of the open XXZ chain II
N. Kitanine, K. Kozlowski, J. M. Maillet +3
We derive compact multiple integral formulas for several physical spin correlation functions in the semi-infinite XXZ chain with a longitudinal boundary magnetic field. Our formula…
Discrete evolution for the zero-modes of the Quantum Liouville Model
L. D. Faddeev, A. Yu. Volkov
The dynamical system for the zero modes of the Liouville Model, which is separated from the full dynamics for the discrete shifts of time , is investigated. The struc…
