A topological space is pathwise-connected iff for every two points
, there is a continuous function
from [0,1] to
such that
and
. Roughly speaking, a space
is pathwise-connected if, for every two points in
, there is a path connecting them. For locally pathwise-connected spaces (which include most "interesting spaces" such as manifolds and CW-complexes), being connected and being pathwise-connected are equivalent, although there are connected spaces which are not pathwise-connected. Pathwise-connected spaces are also called 0-connected.
