Absorption conjecture for crossed products by compact group actions

About 12 years old · traced to

Let GG be a second-countable compact group, let AA be a separable unital C∗C^*-algebra, and let α ⁣:G→Aut⁡(A)\alpha\colon G\to\operatorname{Aut}(A) be an action of GG on AA with finite Rokhlin dimension with commuting towers. Let D\mathcal{D} be a strongly self-absorbing C∗C^*-algebra and suppose that AA is D\mathcal{D}-absorbing. Absorption conjecture. Then A⋊αGA\rtimes_\alpha G is D\mathcal{D}-absorbing. The conjecture generalizes the paper's preservation results for Jiang–Su absorption under compact group actions. Its status is not resolved in the supplied text.
