Types of almost continuity
1983
Proceedings of the American Mathematical Society
The differences for properties of the range space/( A') are considered for functions f: X -Y, where / is almost continuous relative to X X Z, and /( X) C Z C Y. It is shown that if / is allowed to be almost continuous relative to X X Z, where A' is a Peano continuum and Z is a locally connected metric space, then /( X) can be any type of subcontinuum of Z. This contrasts the known results for the case where Z=f(X) and almost continuity is relative to XXf(X). Outer almost continuous retracts (f:
