In algebraic geometry, the abundance conjecture is a conjecture in birational geometry, more precisely in the minimal model program, stating that for every projective variety <math>X</math> with Kawamata log terminal singularities over a field <math>k</math> if the canonical bundle <math>K_X</math> is nef, then <math>K_X</math> is semi-ample.
