where \(\mu _{X_t}\) is the law of \(X_t\). The existence of solutions is demonstrated when \(\sigma \) satisfies certain non-degeneracy and continuity assumptions, and when b meets some integrability conditions, and continuity requirements in the (generalized) total variation distance. Furthermore, uniqueness is established under additional continuity assumptions of a Lipschitz type.
