A thorny path of field theory: from triviality to interaction and confinement
I. M. Suslov
Summation of the perturbation series for the Gell-Mann--Low function β(g) of ϕ^4 theory leads to the asymptotics β(g)=β_\infty g^αat g\to\infty, where α\approx 1 for space dimensio…
Renormalization Group Functions of ϕ^4 Theory from High-Temperature Expansions
I. M. Suslov
It has been previously shown that calculation of renormalization group (RG) functions of the scalar ϕ^4 theory reduces to the analysis of thermodynamic properties of the Ising mode…
Asymptotic Behavior of the \Beta Function in the Φ^4 Theory: A Scheme Without Complex Parameters
Igor M. Suslov
The previously obtained analytical asymptotic expressions for the Gell-Mann - Low function β(g) and anomalous dimensions of ϕ^4 theory in the limit g\to\infty are based on the para…
Is ϕ^4 theory trivial ?
I. M. Suslov
The four-dimensional ϕ^4 theory is usually considered to be trivial in the continuum limit. In fact, two definitions of triviality were mixed in the literature. The first one, intr…
Quantum Electrodynamics at Extremely Small Distances
I. M. Suslov
The asymptotics of the Gell-Mann - Low function in QED can be determined exactly, β(g)= g at g\to\infty, where g=e^2 is the running fine structure constant. It solves the problem o…
Analytical asymptotics of β-function in ϕ^4 theory (end of the "zero charge" story)
I. M. Suslov
Reconstruction of the β-function for ϕ^4 theory, attempted previously by summation of perturbation series, leads to asymptotics β(g)=β_\infty g^αat g\to\infty, where α\approx 1 for…
