Given a locally compact group G, the full C*-algebra C*(G) and reduced C*-algebra C*_r(G) are well known. But already Eymard in his fundamental paper in 1964 realized that there are a lot of algebras in between.
Until recently these “exotic” C*-algebras in between has received little attention. I will try to give a survey of these algebras and explain how they give rise to exotic crossed products and exotic coactions.
However, we have more questions than answers.
