TL;DR: In this article, the Bardeen model is interpreted as the gravitational field of a nonlinear magnetic monopole, i.e., as a magnetic solution to Einstein equations coupled to a non-linear electrodynamics.

TL;DR: Using a nonlinear electrodynamics coupled to General Relativity, a new regular exact black hole solution was found in this paper, where the nonlinear theory reduces to the Maxwell one in the weak limit, and the solution corresponds to a charged black hole for |q|≤2s c m≈1.05 m, with metric, curvature invariants, and electric field regular everywhere.

TL;DR: In this paper, a non-singular exact black hole solution in General Relativity was presented, which corresponds to a charged black hole with |q| ≤ 2scm ≈ 0.6 m, having metric, curvature invariants and electric field bounded everywhere.

TL;DR: In this paper, the power spectra of cosmological perturbations were calculated for two classes of inflation models, i.e., chaotic inflation with a monomial potential, power-law inflation and inflation at a maximum.

TL;DR: In this paper, a non-singular exact black hole solution in General Relativity was presented, which corresponds to a charged black hole with |q| \leq 2s_c m \approx 0.6 m, having metric, curvature invariants and electric field bounded everywhere.
