Abstract
A $\mathbb Q$-conic bundle germ is a proper morphism from a threefold with only terminal singularities to the germ $(Z \ni o)$ of a normal surface such that fibers are connected and the anti-canonical divisor is relatively ample. Building upon our previous paper, we prove the existence of a Du Val anti-canonical member under the assumption that the central fiber is irreducible.
