Invertible Spectra in the <i>E</i> (<i>n</i> )-Local Stable Homotopy Category
Suppose C is a category with a symmetric monoidal structure, which we will refer to as the smash product. Then the Picard category is the full subcategory of objects which have an inverse under the smash product in C, and the Picard group Pic(C) is the collection of isomorphism classes …
