The decomposition conjecture for shoreless continua
The decomposition conjecture for shoreless continua
Let be a continuum with no shore points, let , and let denote a decomposition into subcontinua. A point is non-coastal in a subcontinuum if it is not a coastal point there. The decomposition conjecture. There is a decomposition
such that
and is non-coastal when treated as a point of each . The claim is intended to make the spot-welding construction of two copies of generic, but the stronger conjecture is false.
