%0 Journal Article %T On physical diffusion and stochastic diffusion %A T. N. Narasimhan %J Mathematics %D 2010 %I arXiv %X Although the same mathematical expression is used to describe physical diffusion and stochastic diffusion, there are intrinsic similarities and differences in their nature. A comparative study shows that characteristic terms of physical and stochastic diffusion cannot be placed exactly in one-to-one correspondence. Therefore, judgment needs to be exercised in transferring ideas between physical and stochastic diffusion. %U http://arxiv.org/abs/1001.2357v2
