Smooth continuum
From Encyclopedia of Mathematics
at a point 
A continuum 
such that for each sequence 
of points of 
converging towards a point 
and each subcontinuum 
containing 
and 
there exist a sequence of subcontinua 
in

, converging towards 
. A continuum that is smooth at each one of its points is called smooth.
Comments
Smoothness has a slightly different definition in the class of uniquely arcwise-connected continua, or dendroids (a continuum 
is uniquely arcwise-connected if for every 
and 
in 
there is a unique arc 
in 
connecting 
and 
). One calls a uniquely arcwise-connected continuum 
smooth if there is a 
such that 
whenever 
in 
. Such a point 
is called an initial point of 
.
