Finite Hilbert stability of (bi)canonical curves

Alper, Jarod; Fedorchuk, Maksym; Smyth, David


We prove that a generic canonically or bicanonically embedded smooth curve has semistable mth Hilbert points for all m = 2. We also prove that a generic bicanonically embedded smooth curve has stable mth Hilbert points for all m = 3. In the canonical case, this is accomplished by proving finite Hilbert semistability of special singular curves with Gm-action, namely the canonically embedded balanced ribbon and the canonically embedded balanced double A2k+1-curve. In the bicanonical case, we...[Show more]
