Query: Curves in Segre threefolds   We study locally Cohen-Macaulay curves of low degree in the Segre threefold
with Picard number three and investigate the irreducible and connected
components respectively of the Hilbert scheme of them. We also discuss the
irreducibility of some moduli spaces of purely one-dimensional stable sheaves
and apply the similar argument to the Segre threefold with Picard number two.
