Symmetry problem 1

  • Alexander G. Ramm Department of Mathematics, Kansas State University 


A symmetry problem is solved. A new method is used. The idea of this methodis to reduce to a contradiction the PDE and the over-determined boundary data on the boundary.The new method allows one to solve other symmetry problems.
