Vesna Stojanoska: The Picard group of spectra of topological modular forms

I will present computations of the Picard groups of several spectra of topological modular forms, with and without level structures, periodic and non-periodic. The toolbox for these computations will consist of descent theory and a technical lemma allowing us to compare stable and unstable information in spectral sequences. This is joint work with Akhil Mathew.
