摘要：Stein degree measures the number of connected components of general fibers of a projective morphism.  A conjecture due to Caucher Birkar asserts that Stein degree of boundary divisors on log Calabi–Yau fibrations is bounded from above.  In this talk, I will present our recent progress that establishes the boundedness of Stein degree, thereby confirming Birkar’s conjecture in the general framework of generalised pairs.  This talk is based on joint work with Caucher Birkar.
