Necessary and sufficient conditions for zero subsets of holomorphic functions
Abstract
Let be a domain in the complex plane, be an extended real function on . If is a non-zero holomorphic function on with an upper constraint on this domain , then it is natural to expect that there must be some upper constraints on the distribution of zeros of this holomorphic function exclusively in terms of the function and the geometry of the domain . We have investigated this question in detail in our previous works in the case when is a subharmonic function and the domain is arbitrary or with a non-polar boundary. The answer was given in terms of limiting the distribution of zeros of from above via the Riesz measure of the subharmonic function . In this article, the function is the difference of subharmonic functions, or a -subharmonic function, and the upper constraints are given in terms of the Riesz charge of this -subharmonic function . These results are also new to a certain extent for the subharmonic function . The case when the domain D is the complex plane is considered separately. For the complex plane, it is possible to reach the criterion level.
