This is going to give you a strongly pseudoconvex neighborhood. That's why I ask what convention you take for the definitions. | |
Feb 27 at 9:18 | comment | added | Doug Liu | Dear @LidingYao, No. A connected open subset of $\mathbb{C}^n$ is Stein iff it is pseudoconvex. I guess that there is a pseudoconvex domain in $\mathbb{C}^n$ which is not strongly pseudoconvex. | |
