摘  要:This series talks are based on classical results about harmonic functions’ frequency, polynomial growth, nodal sets. We mainly follow Lin-Garofalo, Colding-Minicozzi, Lin-Han, Cheeger-Naber-Valtorta, Logunov. We emphasize the relation between the existence of non-trivial harmonic function, frequency, the size of nodal sets. The lectures will be detailed in techniques, but also informal with many open questions among the talks.
