Rigidity for local holomorphic isometric maps from the complex unit ball to reducible bounded symmetric domains
Year: 2026
Type: preprint
Abstract: Let $U$ be a connected open subset of the complex unit ball $B^n$, $n\geq2$, and let $F_i: U \to Ω_i$ be non-constant holomorphic maps into irreducible bounded symmetric domains. We prove that if $F=(F_1, \cdots, F_m)$ is a holomorphic isometric map from $U$ to the product of $Ω_i$, then every $F_i$ extends to a proper holomorphic isometric embedding up to a positive constant from $B^n$ into $Ω_i$.
