The Orbifold Mordell Conjecture for orbifold curves
Let be a smooth proper orbifold curve over a number field , where , and call Mordellic if, after every finite field extension and for every regular finitely generated integral model, the set of orbifold maps from the model's base is finite. Orbifold Mordell Conjecture. If is of general type, then is Mordellic. The conjecture is open for every general-type orbifold curve whose boundary has only finite multiplicities and whose underlying curve has genus at most one.
