Geometry of W-algebras from the affine Lie algebra point of view
Z. Bajnok, D. Nogradi
To classify the classical field theories with W-symmetry one has to classify the symplectic leaves of the corresponding W-algebra, which are the intersection of the defining constr…
Symplectic leaves of W-algebras from the reduced Kac-Moody point of view
Z. Bajnok, D. Nogradi
The symplectic leaves of W-algebras are the intersections of the symplectic leaves of the Kac-Moody algebras and the hypersurface of the second class constraints, which define the…
Nonperturbative study of the two-frequency sine-Gordon model
Z. Bajnok, L. Palla, G. Takacs +1
The two-frequency sine-Gordon model is examined. The focus is mainly on the case when the ratio of the frequencies is 1/2, given the recent interest in the literature. We discuss t…
The k-folded sine-Gordon model in finite volume
Z. Bajnok, L. Palla, G. Takacs +1
We consider the k-folded sine-Gordon model, obtained from the usual version by identifying the scalar field after k periods of the cosine potential. We examine (1) the ground state…
