Harmonic and Subharmonic Functions,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 . is a holomorphic function, then log | . | is a subharmonic function.

How do you create a financial model?, the function is in fact the restriction to Ω of a holomorphic function defined on a larger open set. The obvious example of a removable isolated singularity comes to mind. Another example occurs when we define the function by a power series expansion, for instance, for . in .(0, 1), we can sum the
