Abstract

In this article, we characterize the holomorphic mappings from Bpn×DmB_{\ell_p^n}\times\mathbb{D}^{m} into Dm\mathbb{D}^{m} for p{2,}p\in \{2,\infty\}. In addition, we give a simple proof for the boundary Schwarz lemma for vector valued holomorphic functions, which also extends the existing result. Also, we obtain the boundary Schwarz lemma for pluriharmonic self-mappings of the unit ball BpnB_{\ell_p^n}, p[2,]p \in [2,\infty]. Furthermore, we establish the boundary rigidity theorem for holomorphic self-mappings of BpnB_{\ell_p^n}, p(1,)p \in (1,\infty).
