Secant varieties: a crossroad of projective geometry, algebra and topology

In this talk I will show how the study of secant varieties, which belongs to the realm of projective geometry, gives important information about the topology of projective varieties and interesting algebraic problems, like interpolation, tensor rank computations, canonical forms, etc. which have also a serious impact in applications.
