Blow-ups of Algebraically Elliptic Manifolds

Prove that the blow-up of an algebraically elliptic manifold along any algebraic submanifold is algebraically elliptic.

Background

The authors review positive results showing that various blow-ups preserve strong dominability and related properties, and that blow-ups of uniformly rational compact manifolds are algebraically elliptic. They note broad evidence suggesting stability of algebraic ellipticity under blow-ups.

Despite this evidence, the general statement that blow-ups of algebraically elliptic manifolds remain algebraically elliptic has not yet been proved, leaving a key birational aspect of algebraic ellipticity open.

References

In view of all these results, it is reasonable to expect that an algebraically elliptic manifold blown up along an algebraic submanifold is algebraically elliptic, but this is yet to be proved.
