我们考虑如何沼泽地标准可能被应用到模型中的标量场有非平凡的动力学条款，特别是在P（X，X）理论的背景下，广泛用于通货膨胀的方法，其替代品，和后期的宇宙加速的问题。通过嵌入这样的理论在规范的多场模型，从原来的理论出现作为一个低能量的有效场论，我们得到沼泽地的限制，并研究在何种情况下，这些可能会被逃避，同时保持宇宙学有趣的现象。我们进一步展示了这些成功是如何与多场图像中的场空间转向现象联系在一起的。我们研究一般问题和特别感兴趣的具体例子，如DBI通货膨胀。
We consider how the swampland criteria might be applied to models in which scalar fields have nontrivial kinetic terms, particularly in the context of P(ϕ,X) theories, popularly used in approaches to inflation, to its alternatives, and to the problem of late-time cosmic acceleration. By embedding such theories in canonical multi-field models, from which the original theory emerges as a low-energy effective field theory, we derive swampland constraints, and study the circumstances under which these might be evaded while preserving cosmologically interesting phenomenology. We further demonstrate how these successes are tied to the phenomenon of turning in field space in the multi-field picture. We study both the general problem and specific examples of particular interest, such as DBI inflation.
