Idea

The 2-periodic version of complex cobordism cohomology theory MU is usually denoted $MP$ (e.g. Lurie lecture 18, example 5).

Properties

As a Thom spectrum

$MP$ may be realized as the Thom spectrum of the universal virtual complex bundle of arbitrary rank over the space $B U \times \mathbb{Z}$ (Lurie lecture 18, Example 5).

Landweber exact functor therem

There is an analogue of the Landweber exact functor theorem for even 2-periodic cohomology theories, with MU replaced by MP (Lurie lecture 18, prop. 11).
