theorem Th15:
  for X being non empty set holds
    C_Normed_Algebra_of_BoundedFunctions(X) is ComplexAlgebra
proof
  let X be non empty set;
  set W=C_Normed_Algebra_of_BoundedFunctions X;
  set V=C_Algebra_of_BoundedFunctions X;
  C_Algebra_of_BoundedFunctions X is ComplexAlgebra;
  hence thesis by Th14;
end;
