Abstract

Let LL be finite extension of Qp\mathbb{Q}_p with ring of integers OL\mathcal{O}_L. I show that periodic topological cyclic homology of OL\mathcal{O}_L, over the base E\mathbb{E}_{\infty}-ring SW(Fq)[z]\mathbb{S}_{W(\mathbb{F}_q)}[z] carries a pp-height one formal group law mod pp that depends on the Eisenstein polynomial of LL over Qp\mathbb{Q}_p for a choice of uniformizer ϖOL\varpi\in \mathcal{O}_L.
