Processes with an arbitrary degree law dependence coefficient in an isotropic space with an arbitrary dimension (I)

The evaluation from above for the non-linear thermoconductivity equation’s exact solution is obtained for the case when temperature conductivity diffusion coefficient $(g)$ dependence on temperature (concentration $C$) is as follows: $g(C)=A C ^n$, where $(1\leq n\leq \infty, A=const).$
