The Hyperelliptic Ζ-function and the Integrable Massive Thirring Model
We provide a treatment of algebro-geometric solutions of the classical massive Thirring system in the framework of the Weierstrass–Klein theory of hyperelliptic functions. We show that the equations of this model generate the characteristic relations of hyperelliptic theory of even hyperelliptic curves, the same role that the KdV equation plays for odd hyperelliptic curves. We also consider the...
متن کاملGeneralized Thirring Models
The Thirring model and various generalizations of it are analyzed in detail. The four-Fermi interaction modifies the equation of state. Chemical potentials and twisted boundary conditions both result in complex fermionic determinants which are analyzed. The non-minimal coupling to gravity does deform the conformal algebra which in particular contains the minimal models. We compute the central c...
متن کاملThe Conformal Points Of The Generalized Thirring Model
In the large N limit, conditions for the conformal invariance of the generalized Thirring model are derived, using two different approaches: the background field method and the Hamiltonian method based on an operator algebra, and the agreement between them is established. A free field representation of the relevant algebra is presented, and the structure of the stress tensor in terms of free fi...
متن کاملA Local and Integrable Lattice Regularization of the Massive Thirring Model
The light–cone lattice approach to the massive Thirring model is reformulated using a local and integrable lattice Hamiltonian written in terms of discrete fermi fields. Several subtle points concerning boundary conditions, normal–ordering, continuum limit, finite renormalizations and decoupling of fermion doublers are elucidated. The relations connecting the six–vertex anisotropy and the vario...

We generalize Toda–like integrable lattice systems to non–symmetric case. We show that they possess the bi–Hamiltonian structure.
