Infinite lattice models by expansion with a non-Gaussian initial approximation
Aleksandr Ivanov, Vasily Sazonov
Recently, a convergent series employing a non-Gaussian initial approximation was constructed and shown to be an effective computational tool for the finite size lattice models with…

Convergent series for lattice models with polynomial interactions
Aleksandr S. Ivanov, Vasily K. Sazonov
The standard perturbative weak-coupling expansions in lattice models are asymptotic. The reason for this is hidden in the incorrect interchange of the summation and integration. Ho…

Convergent Perturbation Theory for the lattice -model
Vladimir V. Belokurov, Aleksandr S. Ivanov, Vasily K. Sazonov +1
The standard lattice perturbation theory leads to the asymptotic series because of the incorrect interchange of the summation and integration. However, changing the initial approxi…
