Invariant measures on the transversal hull of cone semigroups and some applications
Danilo Polo Ojito, Emil Prodan, Tom Stoiber
Let $\LL_{\bf v}\subset \Z^D$ be a suitable cone semigroup and $\A_{\bf v}$ its reduced semigroup -algebra. In this paper, we compute the $\LL_{\bf v}$-invariant measures in t…

C*-framework for higher-order bulk-boundary correspondences
Danilo Polo Ojito, Emil Prodan, Tom Stoiber
A typical crystal is a finite piece of a material which may be invariant under some point symmetry group. If it is a so-called intrinsic higher-order topological insulator or super…
