  • Beschreibung: <p>In an earlier paper, the authors constructed a natural map, called the sigma orientation, from the Thorn spectrum MU<tex-math>$\left\langle 6 \right\rangle$</tex-math>to any elliptic spectrum. MU<tex-math>$\left\langle 6 \right\rangle$</tex-math>is an<tex-math>$H_\infty $</tex-math>ring spectrum, and in this paper we show that if (E, C, t) is the elliptic spectrum associated to the universal deformation of a supersingular elliptic curve over a perfect field of characteristic p &gt; 0, then the sigma orientation is a map of<tex-math>$H_\infty $</tex-math>ring spectra.</p>
