Summary
Relations between solutions of homogeneous wave equations for different dimensions are discussed. Idem for Green’s functions. A similar discussion is given for the Klein-Gordon equations. Relations with solutions for powers of D’Alembertian and Kleinian are also discussed. Their importance for the understanding of the relations between analytic and dimensional regularization is briefly mentioned.
