In this article, we present a classification of toric \(b^{m}\) -symplectic manifolds and outline a program for the classification of semitoric singular symplectic manifolds. As a testing ground, we begin with the case of \(b\) -symplectic manifolds, where a Delzant-type theorem for toric actions has already been established [13]. Building on this foundation, we extend the framework to the broader setting of \(b^{m}\) -symplectic manifolds, thereby establishing the first classification result for \(b^{m}\) -toric manifolds. This achievement lays the groundwork for a conjectural classification theory of semitoric systems in dimension four on \(b^{m}\) -symplectic manifolds. Furthermore, by employing the reduction theory developed in [21], we propose a conjectural classification scheme for higher-dimensional semitoric manifolds, aiming to generalize the Pelayo – Vũ Ngọc classification program [32, 33] to the singular \(b^{m}\) -setting.
