Original · EN
We present the critical exponents νₗ₂, ηₗ₂ and γₗ for an m-axial Lifshitz point at second order in an εₗ expansion. We introduced a constraint involving the loop momenta along the m-dimensional subspace in order to perform two- and three-loop integrals. The results are valid in the range 0 ≤ m < d. The case m=0 corresponds to the usual Ising-like critical behavior.
