Abstract

Using the Hill-Hopkins-Ravenel norm, one can produce a Q8Q_8-spectrum NC2Q8MURN_{C_2}^{Q_8} \text{MU}\mathbb{R}, where Q8Q_8 is the quaternion group. Working towards a computation of the slice spectral sequence for NC2Q8MURN_{C_2}^{Q_8} \text{MU}\mathbb{R}, we compute the zero slice of NC2Q8MURN_{C_2}^{Q_8} \text{MU}\mathbb{R} and a bigraded subring of the RO(Q8)\text{RO}(Q_8)-graded homotopy Mackey functors of this slice.
