We present a self-gravitating, analytic and globally regular Skyrmion solution of the Einstein–
Skyrme system with winding number w=±1, in presence of a cosmological constant. The …

In this paper, we consider third-order Lovelock gravity with a cosmological constant term in
an n-dimensional spacetime M 4× K n-4, where K n-4 is a constant curvature space. We …

A bstract It is show that one can derive a novel BPS bound for the gauged Non-Linear-
Sigma-Model (NLSM) Maxwell theory in (3+ 1) dimensions which can actually be saturated …

A consistent ansatz for the Skyrme model in (3+ 1 3+ 1)-dimensions which is able to reduce
the complete set of Skyrme field equations to just one equation for the profile in situations in …

We construct analytic (3+ 1)-dimensional inhomogeneous and topologically nontrivial pion
systems using chiral perturbation theory. We discuss the effect of isospin asymmetry with …

Using a remarkable mapping from the original (3+ 1) dimensional Skyrme model to the Sine-
Gordon model, we construct the first analytic examples of Skyrmions as well as of Skyrmions …

We construct exact, regular and topologically nontrivial configurations of the coupled
Einstein-nonlinear sigma model in (3+ 1) dimensions. The ansatz for the nonlinear SU (2) …

We construct the first analytic self-gravitating Skyrmions with higher Baryon charge in four
dimensions for the SU (3)-Skyrme–Einstein-Λ Λ theory by combining the generalized …

We construct the first analytic examples of topologically nontrivial solutions of the (3+ 1)-
dimensional U (1) gauged Skyrme model within a finite box in (3+ 1)-dimensional flat space …

We show that one can reduce the coupled system of seven field equations of the (3+ 1)-
dimensional gauged Skyrme model to the Heun equation (which, for suitable choices of the …
