Abstract : A theoretical procedure is described for resolving initialboundary value problems relative to partial differential equations of the diffusion type in cases of axial symmetry. This entails a single integral transformation or series expansion with Bessel functions depending on the radial coordinate and uses a full solution of the reduced form of the diffusion equation involving the axial coordinate and the time. Applications are made to problems of heat conduction, electrical conductivity and viscous fluid motion. (Author)
