  author={Korkut Bardakci and Martin B. Halpern},
We briefly recall the historical environment around our 1971 and 1975 constructions of current-algebraic internal symmetry on the open string. These constructions included the introduction of world-sheet fermions, the independent discovery of affine Lie algebra in physics (level one of affine su(3)), the first examples of the affine-Sugawara and coset constructions, and finally – from compactified spatial dimensions on the string – the first vertexoperator constructions of the fermions and… Expand


Equivalent-boson method and free currents in two-dimensional gauge theories
In the context of the equivalent-boson method a large variety of quark- gluon theories are studied in two dimensions. A number of simple results are obtained, including the fact that gluonExpand
Virasoro algebras and coset space models
Abstract A previous construction of unitary representations of the Virasoro algebra is extended and interpreted physically in terms of a coset space quark model. The quaternionic projective spacesExpand
Heterotic string theory (I). The free heterotic string
A new theory of closed orientable superstrings is constructed as a chiral combination of the closed D = 26 bosonic and D = 10 fermionic strings. The resulting ten-dimensional theory is N = 1Expand
Dual Theory for Free Fermions
A wave equation for free fermions is proposed based on the structure of the dual theory for bosons. Its formal properties preserve the role played by the Virasoro algebra. Additional Ward-likeExpand
Bosonization of the SU(N) Thirring models
Abstract Bosonization is applied to the SU( N ) Thirring models, and interesting relations between various two-dimensional field theories arise. In particular, we show that the SU(2) model isExpand
Current Algebra and Wess-Zumino Model in Two-Dimensions
We investigate quantum field theory in two dimensions invariant with respect to conformal (Virasoro) and non-abelian current (Kac-Moody) algebras. The Wess-Zumino model is related to the special caseExpand
Infinite Conformal Symmetry in Two-Dimensional Quantum Field Theory - Nucl. Phys. B241, 333 (1984)
We present an investigation of the massless, two-dimentional, interacting field theories. Their basic property is their invariance under an infinite-dimensional group of conformal (analytic)Expand
Making the massless string massive
We investigate the possibility of associating a finite rest mass density with the relativistic string at the classical level. We choose a modification of the massless Lagrangian which reduces in theExpand
Dual-resonance models
Abstract Dual-resonance models are treated both as S -matrix theories and as systems of interacting strings. We show how Veneziano was able to construct a dual four-point amplitude with narrowExpand
New gauge identities in dual quark models
Abstract It is found that a simple dual quark model posseses a large number of gauge identities with a suitable choice of external particles. These identities eliminate a large number of undesirableExpand
