Renormalization Scheme Dependence, RG Flow and Borel Summability in \(\phi^4\) Theories in \(d<4\)

Renormalization group (RG) and resummation techniques have been used in \(N\)-component \(\phi^4\) theories at fixed dimensions below four to determine the presence of non-trivial IR fixed points and to compute the associated critical properties. Since the coupling constant is relevant in \(d
