Title: Cartan subalgebras in dimension drop algebras

Abstract: We study Cartan subalgebras in (stabilised) dimension drop algebras and obtain a complete classification up to conjugacy by an automorphism in dimension drop algebras with coprime parameters. Moreover, we show that in this setting two Cartan subalgebras are conjugate if and only if their spectrum is homeomorphic, providing the tamest possible classification result for C*-algebraic Cartan subalgebras.
