Abstract

A hypersurface X (resp., a pair of hypersurfaces {Y,Z}) is called a hypersurface (resp., a pair of hypersurfaces) of uniqueness for holomorphic mappings from C to PN(C) if for two non-degenerate holomorphic mappings f,g from C to PN(C), the condition νf(X)=νg(X) (resp., νf(Y)=νg(Y), νf(Z)=νg(Z)) implies f≡g, where for a mapping φ, νφ(V) denotes the pull-back of a divisor V in PN(C) by φ. In this paper, we give some classes of hypersurfaces and of pairs of hypersurfaces of uniqueness for holomorphic mappings from C to PN(C).
