TITLE	On Movable Cones of Some Calabi-Yau Threefolds of Picard Rank Two
ABSTRACT	本次演講取消 The birational geometry of Calabi-Yau threefolds is intricate even with many advances in modern higher dimension geometry. For example, Reid's fantasy and the Morrison-Kawamata cone conjecture are only partially solved. In this talk, we report a recent joint work with Atsushi Ito (Okayama) and Sz-Sheng Wang (Academic Sinica at Taiwan), in which we describe explicitly the movable cones of a class of Calabi-Yau threefolds of Picard rank two. These examples may shed some light on the above-mentioned conjectures.
