## Main Question or Discussion Point

i know that idea would seem a bit weird but,

let us suppose we have a surface or volume in d- dimension, here d can be any real number (fractional dimension) the question is that we do not know what value 'd' is

[tex] \frac{\partial \phi}{\partial t} = D\,\Delta \phi [/tex]

D is a diffusion (constant) coefficient and 'nabla' is the Laplacian in d- dimension.

my question is if we performed a simulation of a 'diffusion process' could we get the value of 'd' , in other words, depending the dimension of space the diffusion process is completely different.
