Abstract

We prove the height two case of a conjecture of Hovey and Strickland that provides a K (n)-local analogue of the Hopkins-Smith thick subcategory theorem. Our approach first reduces the general conjecture to a problem in arithmetic geometry posed by Chai. We then use the Gross-Hopkins period map to verify Chai's Hope at height two and all primes. Along the way, we show that the graded commutative ring of completed cooperations for Morava E-theory is coherent, and that every finitely generated Morava module can be realized by a K (n)-local spectrum as long as 2p - 2 > n(2) + n. Finally, we deduce consequences of our results for descent of Balmer spectra.
