Understand

Attractor inflation is a particularly robust framework for developing inflationary models that are insensitive to the details of the potential.

Such models are most often considered in the metric formulation of gravity.
However, non-minimal models may not necessarily maintain their attractor nature in the Palatini formalism where the connection is independent of the metric.
In this work, we employ the $\beta$-function formalism to classify the strong coupling limit of inflationary models in both the metric and the Palatini approaches.
