A large number of properties of hololomorphic functions (maximum principle, Schwarz’s lemma, convexity properties, etc.) still hold for a much larger class of functions. It is the class of subharmonic functions (see Definition 4.4.1). The relation between these two classes of functions is given by the fact that if f is a holomorphic function, then log | f | is a subharmonic function.
