Abstract

Nevanlinna showed that two non-constant meromorphic functions on C must be linked by a Möbius transformation if they have the same inverse images counted with multiplicities for four distinct values. After that this result is generalized by Gundersen to the case where two meromorphic functions share two values ignoring multiplicity and share other two values with multiplicities truncated by 2. Previously, the first author proved that for , there are at most two linearly non-degenerate meromorphic mappings of into sharing hyperplanes ingeneral position ignoring multiplicity. In this article, we will show that if two meromorphic mappings f and g of into share hyperplanes ignoring multiplicity and another hyperplane with multiplicities truncated by then the map is algebraically degenerate.
