Online Minisymposium on Low-rank Geometry and Computation

This is an online minisymposium on geometry and numerical approximation of low-rank matrices and tensors. The aim is to exchange latest research results in a format that encourages discussion and interaction.

The number of participants will be limited. Registration is closed.
