Abstract: We prove, among other results, that $\min(u,v)$ is plurisubharmonic (psh) when $u,v$ belong to a family of functions in $ psh(D)\cap\Lambda_{\alpha}(D),$ where $\Lambda_{\alpha}(D)$ is the $\alpha$-Lipchitz functional space with $1<\alpha<2.$ Then we establish a new characterization of holomorphic functions defined on open sets of $\mathbb{C}^n.$
Keywords: maximum principle, plurisubharmonic function
