[en] Starting from Landau Hamiltonian, using a summation procedure with some other assumptions, a proof of scaling for any continuous dimension below four is given. The critical exponents can be calculated by standard renormalization group arguments. The Lowest-order calculation, which is of course unable to locate the ficed point, leads in three dimensions to an expression for eta and γ which is that, if γ is fixed to be 1.25, then eta turns out to be 0.12
