Picard Group of TMF (and Infinity Categories)

The aim of this small meeting is to bring together young researchers from different areas of homotopy theory, in particular those interested in learning about Picard groups and spaces of ring spectra, and to learn a new topic in a pleasant, informal atmosphere.
