Query: On kinetic energy stabilized superconductivity in cuprates   The possibility of kinetic energy driven superconductivity in cuprates as was
recently found in the $tJ$ model is discussed. We argue that the violation of
the virial theorem implied by this result is serious and means that the
description of superconductivity within the $tJ$ model is pathological.
