Meaning of Ahlfors theory | Babel Free
Definitions
A geometric counterpart to Nevanlinna theory that extends the applicability of the concept of covering surface (of a topological space) by defining a covering number (a generalised "degree of covering") applicable to any bordered Riemann surface equipped with a conformal Riemannian metric.
Examples
“In this chapter we use⟳ Ahlfors' theory of covering surfaces to obtain⟳ results on the functional n(r,a).”
“Terms of the form⟳ o(A(r)) in Ahlfors theory are given in the form⟳ cD(r) where c is a constant.”
“The Ahlfors theory itself describes covering of curves or domains, but not covering of distinct, complex values #92;boldsymbol#123;a#125;.”
