Duality Symmetry Group of Two Dimensional Heterotic String Theory
نویسنده
چکیده
The equations of motion of the massless sector of the two dimensional string theory, obtained by compactifying the heterotic string theory on an eight dimensional torus, is known to have an affine o(8, 24) symmetry algebra generating an O(8, 24) loop group. In this paper we study how various known discrete Sand T duality symmetries of the theory are embedded in this loop group. This allows us to identify the generators of the discrete duality symmetry group of the two dimensional string theory. TIFR-TH-95-10 hep-th/9503057 March, 1995

Heterotic-Type II String Duality and the H-Monopole Problem
Since T-duality has been proved only perturbatively and most of the heterotic states map into solitonic, non-perturbative, type II states, the 6-dimensional string-string duality between the heterotic string and the type II string is not sufficient to prove the S-duality of the former, in terms of the known T-duality of the latter. We nevertheless show in detail that the perturbative T-duality,...
متن کاملStrong-weak Coupling Duality in Three Dimensional String Theory
Following an old result of Marcus and Schwarz we argue that in the heterotic string theory compactified on a seven dimensional torus, the target space duality group O(7,23;Z) and the strong-weak coupling duality transformations combine into the group O(8,24;Z). We discuss symmetry of the combined spectrum of elementary particles and solitons in the theory, and also show that the existence of th...
متن کاملOn Target-space Duality in P–branes
We study the target-space duality transformations in p–branes as transformations which mix the worldvolume field equations with Bianchi identities. We consider an (m + p + 1)-dimensional spacetime with p + 1 dimensions com-pactified, and a particular form of the background fields. We find that while a GL(2) = SL(2) × R group is realized when m = 0, only a two parameter group is realized when m ...
متن کاملAnomalous U(1) Gauge Symmetries and Heterotic - Type I/ii String Duality∗
Anomalous U(1) gauge symmetries can appear both in heterotic and type I string theories. In the heterotic case we find a single anomalous U(1), while in open string theories several such symmetries can appear. Nonetheless, there is a conjectured duality symmetry that might connect these two theories. We review the properties of anomalous gauge symmetries in various string theories as well as th...
متن کاملMaximally supersymmetric string theories in D<10.
The existence of maximally supersymmetric solutions to heterotic string theory that are not toroidal compactifications of the ten-dimensional superstring is established. We construct an exact fermionic realization of an N=1 supersymmetric string theory in D=8 with non-simply-laced gauge group Sp(20). Toroidal compactification to six and four dimensions gives maximally extended supersymmetric th...
