Calculating obstruction groups for e ring spectra

Research output: Chapter in Book/Report/Conference proceedingConference contribution


We describe a special instance of the Goerss–Hopkins obstruction theory, due to Senger, for calculating the moduli of E ring spectra with given mod-p homology. In particular, for the 2-primary Brown–Peterson spectrum we give a chain complex that calculates the first obstruction groups, locate the first potential genuine obstructions, and discuss how some of the obstruction classes can be interpreted in terms of secondary operations.
