Maximum modulus theorem in complex analysis

WebThe Maximum-Modulus Theorem is important in the applications of complex variable theory. The theorem has only been proved for regular functions, but it is also true for functions that are not one-valued. The chapter discusses the Phragmén-Lindelöf extension. It presents a theorem on the number of zeros of a bounded function.

WebWe show below that the strong form of the maximum modulus theorem always holds for a B-space X if and only if each point of norm one is a "complex extreme point" of the unit sphere of X. In particular, the theorem holds for strictly convex (i.e. rotund) spaces. Web10 mei 2024 · In mathematics, the Borel–Carathéodory theorem in complex analysis shows that an analytic function may be bounded by its real part.
