The string partition function in Hull’s doubled formalism
T-duality is one of the essential elements of string theory. Recently, Hull has developed a formalism where the dimension of the target space is doubled so as to make T-duality manifest. This is then supplimented with a constraint equation that allows the connection to the usual string sigma model. This paper analyses the partition function of the doubled formalism by interpreting the constaint...
متن کاملSuperstring partition functions in the doubled formalism
Computation of superstring partition functions for the non-linear sigma model on the product of a two-torus and its dual within the scope of the doubled formalism is presented. We verify that it reproduces the partition functions of the toroidally compactified type–IIA and type–IIB theories for appropriate choices of the GSO projection.
متن کاملTopological Partition Function and String-String Duality
The evidence for string/string-duality can be extended from the matching of the vector couplings to gravitational couplings. In this note this is shown in the rank three example, the closest stringy analog of the Seiberg/Witten-setup, which is related to the Calabi-Yau WP 4 1,1,2,2,6(12). I provide an exact analytical verification of a relation checked by coefficient comparison to fourth order ...
متن کاملThe Partition Function of 2D String Theory
We derive a compact and explicit expression for the generating functional of all correlation functions of tachyon operators in 2D string theory. This expression makes manifest relations of the c = 1 system to KP flow and W 1+∞ constraints. Moreover we derive a One of the beautiful aspects of the matrix-model formulation of c < 1 string theory is that it gives a natural and mathematically precis...
متن کاملDoubled Formalism, Complexification and Topological σ-Models
We study a generalization of the Alexandrov-Kontsevich-Schwarz-Zaboronsky (AKSZ) formulation of the Aand B-models which involves a doubling of coordinates, and can be understood as a complexification of the Poisson σ-model underlying these. In the flat space limit the construction contains models obtained by twisting an N=2 supersymmetric σ-model on Hull’s doubled geometry. The curved space gen...
