Query: An estimate on the nodal set of eigenspinors on closed surfaces   We use a modified Bochner technique to derive an inequality relating the
nodal set of eigenspinors to eigenvalues of the Dirac operator on closed
surfaces. In addition, we apply this technique to solutions of similar
spinorial equations.
