Adjunction termination implies uniruledness
Adjunction termination implies uniruledness
Let be a smooth projective variety of dimension over , with canonical divisor , and let be an effective divisor. Say that adjunction terminates in the classical sense for if there exists an integer such that
for every integer . Adjunction termination conjecture. If adjunction terminates in the classical sense for , then is uniruled. The condition implies that has negative Kodaira dimension, and the conjecture reflects the expectation that varieties of negative Kodaira dimension are uniruled; the statement is presented as an open question.
