On generalized Tian Ji's horse racing strategy

Tian Ji’s horse racing strategy, a famous Chinese legend, constitutes a promising concept to be applied to important issues in today’s competitive environment; this strategy is elaborated on and analyzed by examining the general case. The mathematical formulation concerning the calculation of winning, drawing or losing combinations and probabilities is presented to illustrate the interesting in...

Generalized Calabi-Yau manifolds

A geometrical structure on even-dimensional manifolds is defined which generalizes the notion of a Calabi-Yau manifold and also a symplectic manifold. Such structures are of either odd or even type and can be transformed by the action of both diffeomorphisms and closed 2-forms. In the special case of six dimensions we characterize them as critical points of a natural variational problem on clos...

Generalized Calabi - Yau Manifolds and the Mirror of a Rigid Manifold

The Z manifold is a Calabi–Yau manifold with b 21 = 0. At first sight it seems to provide a counter example to the mirror hypothesis since its mirror would have b 11 = 0 and hence could not be Kähler. However by identifying the Z manifold with the Gepner model 1 9 we are able to ascribe a geometrical interpretation to the mirror, ˜ Z, as a certain seven-dimensional manifold. The mirror manifold...

On the Generalized Casson Invariant

The path integral generalization of the Casson invariant as developed by Rozansky and Witten is investigated. The path integral for various three manifolds is explicitly evaluated. A new class of topological observables is introduced that may allow for more effective invariants. Finally it is shown how the dimensional reduction of these theories corresponds to a generalization of the topologica...

On Deformations of Generalized Complex Structures: the Generalized Calabi-Yau Case

We prove an analog of the Tian-Todorov theorem for twisted generalized Calabi-Yau manifolds; namely, we show that the moduli space of generalized complex structures on a compact twisted generalized Calabi-Yau manifold is unobstructed and smooth. We also construct the extended moduli space and study its Frobenius structure. The physical implications are also discussed. CALT-68-2569
