Query: Supersingular curves on Picard modular surfaces modulo an inert prime   We study the supersingular curves on Picard modular surfaces modulo a prime
$p$ which is inert in the underlying quadratic imaginary field. We analyze the
automorphic vector bundles in characteristic $p$, and as an application derive
a formula relating the number of irreducible components in the supersingular
locus to the second Chern class of the surface.
