论文摘要
我们在三个维度上研究了Skyrme模型的几个变形，并具有任意重型电荷的自偶联扇区。我们表明，对于一个背景指标的家庭以及依赖野外耦合的家族，该模型具有一个BPS扇区，可能具有任何拓扑费用。我们还研究了有无限BPS扇区的引力案例，但前提是将宇宙常数添加到模型中。
We study several deformations of the Skyrme model in three dimensions with self-dual sectors of arbitrary baryonic charge. We show that, for a family of background metrics as well as for a family of field dependent couplings, the model has one BPS sector, which may have any topological charge. We also study the gravitating case, where there are infinite BPS sectors, provided that a cosmological constant is added to the model.
