Connected Sum
The connected sum 
of 
-manifolds 
and 
is formed by deleting the interiors of -Balls 
in 
and attaching the resulting punctured Manifolds 
to eachother by a Homeomorphism 
, so
is required to be interior to 
and 
bicollared in to ensure that the connected sum isa Manifold.The connected sum of two Knots is called a Knot Sum.
