Query: Matrix-valued Bratu equation associated with the symmetric domains of
  type BDI and CI   A formulation of the exponential matrix solution of the matrix-valued Bratu
equation is given, based on the structure of the symmetric domain of type BDI.
Moreover, an analog for the symmetric domain of type CI is given.
