On the maximum modulus principle and the identity theorem in arbitrary dimension

Description

We prove an identity theorem for Gâteaux holomorphic functions on polygonally connected 2-open sets, which yields a very general maximum norm principle and a sublinear “max-min” principle. All results apply in particular to vector-valued functions which are holomorphic (in any sense that implies Gâteaux holomorphy) on domains in Hausdorff locally convex spaces.
