Each model of diffusion expresses the diffusion flux with the use of concentrations, densities and their derivatives. Flux is a vector representing the quantity and direction of transfer. Given a small area with normal , the transfer of a physical quantity through the area per time is where is the inner product and is the little-o notation.
