Abstract

With the help of variational perturbation theory we continue the renormalization constants $\phi^4$ -theories in $4- \epsilon$ dimensions to strong bare couplings $g_0$ and find their power behavior in $g_0$ , thereby determining all critical exponents without renormalization group techniques.
