The $C_2$–spectrum $\mathrm{Tmf}_1(3)$ and its invertible modules

Michael A Hill and Lennart Meier

Algebraic & Geometric Topology 17 (2017) 1953–2011
Abstract

We explore the C2–equivariant spectra Tmf1(3) and TMF1(3). In particular, we compute their C2–equivariant Picard groups and the C2–equivariant Anderson dual of Tmf1(3). This implies corresponding results for the fixed-point spectra TMF0(3) and Tmf0(3). Furthermore, we prove a real Landweber exact functor theorem.
