The purpose of this paper is to study the relation between the |$C^0$| -topology and the topology induced by the spectral norm on the group of Hamiltonian diffeomorphisms of a closed symplectic manifold. Following the approach of Buhovsky–Humilière–Seyfaddini, we prove the |$C^0$| -continuity of the spectral norm for complex projective spaces and negative monotone symplectic manifolds. The case of complex projective spaces provides an alternative approach to the |$C^0$| -continuity of the spectral norm proven by Shelukhin. We also prove a partial |$C^0$| -continuity of the spectral norm for rational symplectic manifolds. Some applications such as the Arnold conjecture in the context of |$C^0$| -symplectic topology are also discussed. [ABSTRACT FROM AUTHOR]
