Extension property for maps from projective manifolds to measure-hyperbolic manifolds

At least 5 years old · documented by

Let XX be a projective b[31mdim⁡(X)b[0mb[31m\dim(X)b[0m-analytically hyperbolic manifold, let YY be a projective manifold with b[31mdim⁡(Y)≥dim⁡(X)b[0mb[31m\dim(Y)\geq\dim(X)b[0m, and let H⊂YH\subset Y be a hypersurface. A holomorphic map f:Y∖H→Xf:Y\setminus H\to X is non-degenerate if its differential has maximal rank at some point.

Extension property. Every non-degenerate holomorphic map

f:Y∖H⟶Xf:Y\setminus H\longrightarrow X

extends to a meromorphic map f:Y⇢Xf:Y\dashrightarrow X.

For projective manifolds of general type, a weaker extension statement is known for non-degenerate maps, while the conjecture predicts meromorphic extension under intermediate hyperbolicity. The property is an analogue of the holomorphic extension theorem for compact complex hyperbolic manifolds.
