Query: Translation and homothetical surfaces in Euclidean space with constant
  curvature   We study surfaces in Euclidean space constructed by the sum of two curves or
that are graphs of the product of two functions. We consider the problem to
determine all these surfaces with constant Gauss curvature. We extend the
results to non degenerate surfaces in Lorentz-Minkowski space.
