==Problem 1: Ginzburg criterion in arbitrary spatial dimension and upper critical dimension ==


The general solution for the correlation function in arbitrary spatial dimension within the mean-field theory can be written as:
<math> G(r) \sim  \frac{e^-{r/\xi}}{r^{d-2}} </math>
assuming that distance <math> r \gg a </math> is much larger than the lattice spacing <math> a </math>.
==Problem 2: ==
