Under flatness assumptions\, the E2-term can be identified with cohomo logy of a certain Hopf algebroid\, giving the spectral sequence its comput ational power. Unfortunately\, this identification fails in many important examples\, such as integral homology or connective Morava K-theory\, maki ng these spectral sequences mysterious and hard to calculate with. In this talk\, I will describe a novel method of identifying these E2-terms in te rms of cohomology in representations of certain quivers. This is based on joint work with Burklund.\n\nTo add this to your calendar\, the ics file f or this seminar is here:\nhttp://math.mit.edu/topology/topology_seminar.ic s\n LOCATION:https://researchseminars.org/talk/MITTop/44/ END:VEVENT END:VCALENDAR
