Nevanlinna theory via holomorphic forms

This paper re-develops the Nevanlinna theory for meromorphic functions on $\mathbb C$ in viewpoint of holomorphic forms. According to our observation, Nevanlinna's can be formulated by a form. Applying this thought Riemann surfaces, one then extends definition using form $\mathscr S$. With new settings, an analogue \emph{weak S$-exhausted surfaces} is obtained, which viewed as generalization classical and D.$
