Title: On the rank preserving property of a linear section and its applications in tensors

Abstract: This talk is motivated by several conjectures on tensor ranks arising from signal processing and complexity theory. In the talk, we will first translate these conjectures into the geometric language, and reduce the problems to the study of a particular property of a linear section of an irreducible nondegenerate projective variety, namely the rank preserving property. Then we will introduce several useful tools and show some results obtained via these tools. This talk is based on a joint work with Lek-Heng Lim.
