  The possibility of rate-induced tipping (R-tipping) away from an attracting
fixed point has been thoroughly explored in 1-dimensional systems. In these
systems, it is impossible to have R-tipping away from a path of quasi-stable
equilibria that is forward basin stable (FBS), but R-tipping is guaranteed for
paths that are non-FBS of a certain type. We will investigate whether these
results carry over to multi-dimensional systems. In particular, we will show
that the same conditions guaranteeing R-tipping in 1-dimension also guarantee
R-tipping in higher dimensions; however, it is possible to have R-tipping away
from a path that is FBS even in 2-dimensional systems. We will propose a
different condition, forward inflowing stability (FIS), which we show is
sufficient to prevent R-tipping in all dimensions. The condition, while
natural, is difficult to verify in concrete examples. Monotone systems are a
class for which FIS is implied by an easily verifiable condition. As a result,
we see how the additional structure of these systems makes predicting the
possibility of R-tipping straightforward in a fashion similar to 1-dimension.
In particular, we will prove that the FBS and FIS conditions in monotone
systems reduce to comparing the relative positions of equilibria over time. An
example of a monotone system is given that demonstrates how these ideas are
applied to determine exactly when R-tipping is possible.
