TL;DR: The generalization of the Dirac monopole solution of Maxwell theory to theories of antisymmetric tensor gauge fields of arbitrary rank is considered and a Dirac quantization condition is derived.
Abstract: We consider the generalization of the Dirac monopole solution of Maxwell theory to theories of antisymmetric tensor gauge fields of arbitrary rank. A Dirac quantization condition is derived. These generalized monopoles are expected to be relevant for models of strings and higher-dimensional extended objects, and perhaps also for Kaluza-Klein theories.

Abstract: We investigate terms with four derivatives in the low-energy action of closed Bose strings. Our analysis is consistent with the possibility that the action involves only curvatures of a connection with torsion. The torsion is provided by the antisymmetric tensor gauge field.

TL;DR: In this article, the authors investigated topological solitons (skyrmions) of four-dimensional supersymmetric nonlinear σ-models with the requirements of supersymmetry and showed that a stable soliton seems possible, but in the absence of a demonstrated lower bound for the mass, the stability of the soliton is unproved.

TL;DR: In this article, a complex version of the Freund-Rubin ansatz is constructed for antisymmetric tensor gauge fields on Calabi-Yau manifolds, which have vanishing stress energy tensors.
