Abstract

In this paper, we construct thin-shell wormholes from a regular Ayon-Beato-Garcia black hole by employing cut and paste formalism and examine their stability. We analyze attractive and repulsive characteristics of the respective thin-shell wormholes. A general equation of state is assumed as a linear perturbation to explore stability of these constructed wormholes with and without cosmological constant. We consider linear, logarithmic and Chaplygin gas models for exotic matter and evaluate stability regions for different values of charge. It is found that the generalized Chaplygin gas model provides maximum stable regions in the de Sitter background while the modified generalized Chaplygin gas and logarithmic gas yield maximum stable regions in the anti-de Sitter spacetime.
