Abstract – Critical slowing down is considered to be an important
indicator for predicting critical transitions in dynamical systems.
Researchers have used it prolifically in the fields of ecology,
biology, sociology, and finance. When a system approaches a critical
transition or a tipping point, it returns more slowly to its stable
attractor under small perturbations. The return time to the stable
state can thus be used as an index, which shows whether a critical
change is near or not. Based on this phenomenon, many methods have
been proposed to determine tipping points, especially in biological
and social systems, for example, related to epidemic spreading,
cardiac arrhythmias, or
even population collapse. In this perspective, we briefly review
past research dedicated to critical slowing down indicators and
associated tipping points, and we outline promising directions for
future research.
