Non-Runge Fatou-Bieberbach Domains in Stein Manifolds with the Density Property
Gaofeng Huang, Frank Kutzschebauch, Feng Rong
Let be a Stein manifold with the density property. We present methods of constructing two kinds of non-Runge Fatou-Bieberbach domains in , which by definition are proper ope…

Untriangular factorization of holomorpic symplectic matrices
Gaofeng Huang, Frank Kutzschebauch, Phan Quoc Bao Tran
We prove that every holomorphic symplectic matrix can be factorized as a product of holomorphic unitriangular matrices with respect to the symplectic form $ \left[\begin{array}{ccc…
