We analyze the asymptotically free massless scalar φ quantum field theory in 6 dimensions, using resurgent asymptotic analysis to find the trans-series solutions which yield the non-perturbative completion of the divergent perturbative solutions to the Kreimer–Connes Hopf-algebraic Dyson–Schwinger equations for the anomalous dimension. This scalar conformal field theory is asymptotically free and has a real Lipatov instanton. In the Hopf-algebraic approach we find a trans-series having an…

New renormalons from analytic trans-series
We study the free energy of integrable, asymptotically free field theories in two dimensions coupled to a conserved charge. We develop methods to obtain analytic expressions for its trans-series
Resonant resurgent asymptotics from quantum field theory
We perform an all-order resurgence analysis of a quantum field theory renormalon that contributes to an anomalous dimension in six-dimensional scalar φ3 theory and is governed by a third-order
Dyson-Schwinger Equations in Minimal Subtraction
We examine selected one-scale Dyson-Schwinger-equations in the minimal subtraction renormalization scheme and dimensional regularization. They are constructed from three different integral kernels;
Cluster expansion and resurgence in Polyakov model
In Polyakov model, a non-perturbative mass gap is formed at leading order semi-classics by instanton effects. By using the notions of critical points at infinity, cluster expansion and Lefschetz
Resummation of quantum radiation reaction and induced polarization
In a previous paper we proposed a new method based on resummations for studying radiation reaction of an electron in a plane-wave electromagnetic field. In this paper we use this method to study the
Accelerating Extremum Seeking Convergence by Richardson Extrapolation Methods
In this paper, we propose the concept of accelerated convergence that has originally been developed to speed up the convergence of numerical methods for extremum seeking (ES) loops. We demonstrate
