摘要

In this paper, we give a result on finiteness of meromorphic mappings from \(\mathbb C^m\) C m into \(\mathbb P^n(\mathbb C)\) P n ( C ) sharing hyperplanes in general position with truncated multiplicities to level \(n\) n . In our result, the number of shared hyperplanes is just \(2n\) 2 n instead of \(2n+1\) 2 n + 1 or \(2n+2\) 2 n + 2 as in the previous results, but the number of involving meromorphic mappings still does not exceed 2.
