Umehara algebra and complex submanifolds of indefinite complex space forms
Xu Zhang, Donghai Ji
The Umehara algebra is studied with motivation on the problem of the non-existence of common complex submanifolds. In this paper, we prove some new results in Umehara algebra and o…

Submanifolds of some Hartogs domain and the complex Euclidean space
Xu Zhang, Donghai Ji
Two Kahler manifolds are called relatives if they admit a common Kahler submanifold with the same induced metrics. In this paper, we show that a Hartogs domain over an irreducible…

Four Kahler Moduli Stabilisation in type IIB Orientifolds with K3-fibred Calabi-Yau threefold compactification
Dieter Lust, Xu Zhang
We present a concrete and consistent procedure to generate one kind of non-perturbative superpotential, including the gaugino condensation corrections and poly-instanton correction…
