Abstract
The author generalises the method of renormalisation by minimal subtraction of dimensional poles to the case of having interacting terms in the Hamiltonian with different critical dimensionalities d'c and dc=dc- sigma , where sigma is a variable parameter of the theory. Results to one-loop order for the random m-component ferromagnet with long-range correlated impurities agree with the theory of Weinrib and Halperin (1983).
