Umehara algebra and complex submanifolds of indefinite complex space forms

X Zhang, D Ji – Annals of Global Analysis and Geometry, 2023

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 obtain some applications. In particular, if a complex manifolds …
