Abstract:：          For a given structured tensor, we can define different notions of ranks. In practice, an important issue about these different ranks is when they coincide. Several conjectures have been proposed in this direction, and are receiving more and more attention recently. In this talk we study the rank preserving property of linear sections of certain varieties, which will imply interesting applications on the above conjectures. This talk is based on a joint work with Lek-Heng Lim.
