Balayage of measures and subharmonic functions on a system of rays. II. Balayage of finite genus and regularity of growth on one ray

Abstract

We expand the classical balayage of measures and subharmonic functions on a system of rays $S$ with a common origin on the complex plane $\mathbb{C}$. This allows for an arbitrary subharmonic function $v$ of finite order on $\mathbb{C}$ build $\delta$-subharmonic function on $\mathbb{C}$, harmonic outside $S$ coinciding with $v$ on $S$ outside the polar set, of the same order of growth as $v$. We give applications to the relationship of the growth of an entire function in $S$ with the distribution of its zeros.
