Group automorphisms of incidence algebras.
… This includes the structure and properties of maximal abelian, normal subgroups, and criteria for solvability and nilpotency. Lastly, we will classify the automorphism group of the group of units when (P,≤) = (Z,≤).

… of Leavitt path algebras that take a given maximal abelian subalgebra (MASA) to the diagonal.

Conformal Boundaries, SPTs, and the Monopole-Fermion Problem
… particular family of boundary states preserving maximal abelian symmetries. We classify all such symmetries, and construct all boundary states preserving them. The most interesting part of the construction involves taking care of the normalisation of states to ensure a consistent spectrum. This …
