Continued functions and perturbation series: Simple tools for convergence of diverging series in $O (n)$ -symmetric $ϕ^{4}$ field theory at weak coupling limit

Venkat Abhignan, R. Sankaranarayanan

We determine universal critical exponents that describe the continuous phase transitions in different dimensions of space. We use continued functions without any external unknown p…
