Completely hyperexpansive tuples of finite order

We introduce and discuss a class of operator tuples, which we call completely hyperexpansive tuples of finite order. This class is in some sense antithetical to the class of completely hypercontractive tuples of finite order studied in the prequel of this paper. Motivated by Shimorin's notion of Cauchy dual operator, we also discuss a transform which sends certain completely hyperexpansive multishifts of finite order k to completely hypercontractive multishifts of respective order.
