https://doi.org/10.4995/agt.2003.2048Keywords:
Approximately continuous functions, I-approximately continuous functions, topology of pointwise convergenceAbstract
We shall show that the space of all approximately continuous functions with the topology of pointwise convergence is not homeomorphic to its category analogue.
