Had he not been taken from us at the Reichenbach Falls, he could perhaps have been contributing to knowledge today, whithout needing to change topic. The periods of asteroid orbits exhibit resonances with the orbit of Jupiter which are still the subject of research, and if the ratios of the principal moments of inertia of an asteroid satisfy some condition which I forget, its rotation about its centre of mass can take the form of chaotic tumbling.
As is well known, Doyle was finally forced to resurrect Holmes after the Reichenbach incident. Though Moriarty was not brought back to life, a new master villain was created in his place: Colonel Sebastian Moran. I think he was said to have been Moriarty's right-hand man. But I don't think he was a mathematician.
