Indecomposable continuum
From Wikipedia, the free encyclopedia
In point-set topology, an indecomposable continuum is a continuum that is not decomposable. That is, it is not the union of any two of its proper subcontinua. The pseudo-arc is an example of a hereditarily indecomposable continuum. L. E. J. Brouwer discovered the first indecomposable continuum in 1910[1].
