摘要
We prove that for a quasiregular semiperfectoid Z(p)(cycl)-algebra R (in the sense of Bhatt-Morrow-Scholze), the cyclotomic trace map from the p-completed K-theory spectrum K (R; Z(p)) of R to the topological cyclic homology TC(R; Z(p)) of R identifies on pi(2) with a q-deformation of the logarithm.
