Syntomic cohomology of Morava K-theory

Abstract

We compute the MU-based syntomic cohomologies, mod (p,v1,,vn+1)(p,v_1,\cdots,v_{n+1}), of all E1\mathbb{E}_1-MU-algebra forms of connective Morava K-theory k(n). As qualitative consequences, we deduce the Lichtenbaum--Quillen conjecture, telescope conjecture, and redshift conjecture for the algebraic K-theories of all E1\mathbb{E}_{1}-S\mathbb{S}-algebra forms of (2pn2)(2p^n-2)-periodic Morava K-theory. Notably, the motivic spectral sequence computing πTC(k(n))p\pi_*TC(k(n))_p is concentrated on at most three lines, independently of nn.
