Topological strings in generalized complex space
A two-dimensional topological sigma-model on a generalized Calabi-Yau target space X is defined. The model is constructed in Batalin-Vilkovisky formalism using only a generalized complex structure J and a pure spinor ρ on X . In the present construction the algebra of Q-transformations automatically closes off-shell, the model transparently depends only on J , the algebra of observables and cor...
متن کاملBlack hole entropy and topological strings on generalized CY manifolds
The H. Ooguri, A. Strominger and C. Vafa conjecture ZBH = |Ztop| is extended for the topological strings on generalized CY manifolds. It is argued that the classical black hole entropy is given by the generalized Hitchin functional, which defines by critical points a generalized complex structure on X. This geometry differs from an ordinary geometry if b1(X) 6= 0. In a critical point the genera...
متن کاملTopological Strings
Following some recent works of Witten, we explore topological non-linear sigma models (TSM). W e construct 2-D topological gravity which is then coupled to the TSM resulting in a topological bosonic string theory. This theory has a nontachyonic vacuum and can be formulated on any even dimensional target manifold which admits some non-trivial topology. It is then shown that the metric independen...
متن کاملGTI-Space: The Space of Generalized Topological Indices
A new extension of the generalized topological indices (GTI) approach is carried out to represent “simple” and “composite” topological indices (TIs) in an unified way. This approach defines a GTI-space from which both simple and composite TIs represent particular subspaces. Accordingly, simple TIs such as Wiener, Balaban, Zagreb, Harary and Randić connectivity indices are expressed by means of ...
