Query: A matrix solution to Maxwell's equations in 2 + 1 dimensional curved
  space: Two examples   In an effort that puts together a paper by Plebanski[1] with a matrix
approach to the solution of Maxwell's equations in flat space by Moses[2],
Maxwell's equations in 2 + 1 dimensional curved space are solved in two
separate cases of the metric given by: a.Banados,Teitelboim and Zanelli[3] and
b.Deser,Jackiw and 'tHooft[4] and Clement[5] to obtain the respective time -
independent solutions;an extension to time - dependent solutions with the same
point of view is also briefly indicated.
