Abstract |
|
We show, at the prime 2, that the Picard group of invertible modules over is cyclic. Here, is the height Lubin–Tate spectrum and its –action is induced from the formal inverse of its associated formal group law. We further show that is Gross–Hopkins self-dual and determine the exact shift. Our results generalize the well-known results when . |
