Dual Hopf orders in group rings of elementary Abelian \(p\)-groups. (Q2583031)

The authors construct a new family of Hopf \(R\)-orders in \(KC_p^n\), where \(K\) is a finite field extension of \(\mathbb{Q}_p\) containing \(\root p\of 1\) with \(R\) as a valuation ring. The paper is based on the second author's PhD thesis and complements previous constructions of Hopf orders by the first author with C.~Greither and R.~G.~Underwood.
