Query: Matrix Li-Yau-Hamilton estimates for the heat equation on Kaehler
  manifolds   We proved a matrix Li-Yau-Hamilton type gradient estimates for the positive
solutin of the heat equation on complete Kaehler manifolds with nonnegative
bisectional curvature. As a consequence we obtain a comparison theorem for the
distance function under this curvature assumption.
