The interchange of radiant energy among diffusely emitting and diffusely reflecting opaque surfaces, separated by radiatively nonparticipating media, is a phenomenon governed by systems of integral equations. It is assumed that temperature fields are known, these systems are linear and may have, as unknown, the local radiosities over each surface considered. The author will develop his discussion for an enclosure composed of M diffusely emitting and diffusely reflecting opaque surfaces. If he assumes that the medium is radiatively nonparticipating, all the energy that leaves a region of a given surface will reach one (or more) of the other (M-1) surfaces and/or itself.
