SOME PARTICULAR CASES OF THE TWO-DIMENSIONAL 
INTEGRODIFFERENTIAL EQUATION OF PARTICLE TRANSFER

Some particlar cases are derived from the integrodifferential 
equation of particle transfer with a constant rate: they are the diffusion 
approximation and a differential equation of diffusion (heat conduction) 
of hyperbolic type with a finite velocity of propagation of perturbations.
