Query: Chekanov-type theorem for spherized cotangent bundles   We prove a Chekanov-type theorem for the spherization of the cotangent bundle
$ST^*B$ of a closed manifold $B$. It claims that for Legendrian submanifolds in
$ST^*B$ the property "to be given by a generating family quadratic at infinity"
persists under Legendrian isotopies.
