The author of this short note formulates two problems for functionals and measures, respectively, which are in some sense connected with the Klein- Gordon equation \[ \square u+cu+bu^ 2+au^ 3=g. \] He gives the corresponding notions of solution and conditions for solvability. Proofs are only sketched.
