Abstract：In this talk, I will introduce three types of Lawson-Osserman cones. They are compositions of a Hopf fibration and standard isometric minimal immersions of degree two. By using Lawlor's criterion, we show that they are area-minimizing. In particular, two undetermined minimal cones given in [LO77] will be shown area-minimizing. This is a joint work with Ling Yang and Yongsheng Zhang.
