The homotopy fixed points of Real spin bordism
Hassan H. Abdallah, Yigal Kamel
We show that the 2-local splitting of spin bordism by Anderson--Brown--Peterson and Stong refines to a -equivariant map in the category of spectra with -action from R…

Products in spin-cobordism
Hassan Abdallah, Andrew Salch
We calculate the mod spin-cobordism ring up to uniform -isomorphism (i.e., inseparable isogeny). As a consequence we get the prime ideal spectrum of the mod spin…

On the nonexistence of a Green functor with values spin bordism and spin bordism
Hassan H. Abdallah, Zachary Halladay, Yigal Kamel
In this note, we show that there does not exist a -ring spectrum whose underlying ring spectrum is and whose -fixed point spectrum is .
