| Summary:

Self-organisation is the spontaneous emergence of spatio-temporal structures
and patterns from the interaction of smaller individual units. Examples are
found across many scales in very different systems and scientific disciplines,
from physics, materials science and robotics to biology, geophysics and
astronomy. Recent research has highlighted how self-organisation can be both
mediated and controlled by confinement. Confinement occurs through interactions
with boundaries, and can function as either a catalyst or inhibitor of
self-organisation. It can then become a means to actively steer the emergence
or suppression of collective phenomena in space and time. Here, to provide a
common framework for future research, we examine the role of confinement in
self-organisation and identify overarching scientific challenges across
disciplines that need to be addressed to harness its full scientific and
technological potential. This framework will not only accelerate the generation
of a common deeper understanding of self-organisation but also trigger the
development of innovative strategies to steer it through confinement, with
impact, e.g., on the design of smarter materials, tissue engineering for
biomedicine and crowd management.
