Brown-Peterson spectra in stable A^1-homotopy theory, by Gabriele Vezzosi

We characterize ring spectra morphism from the algebraic cobordism spectrum MGL to an oriented spectrum E (in the sense of Morel) via formal group laws on the "topological" subring E^* of E^**. This result is then used to construct BP-spectra in essentially the same way Quillen did for the complex-oriented topological case
