Abstract:

In 1947, W.H. Gottschalk proved that no dendrite is the continuous, exactly $k$-to-1 image of any continuum if $k \geq 2$. Since that time, no other class of continua has been shown to have this same property. It is shown that no hereditarily indecomposable tree-like continuum is the continuous, exactly $k$-to-1 image of any continuum if $k \geq 2$.
