Properties of hyperconnected spaces
A topological space is said to be hyperconnected if every pair of nonempty open subsets has nonempty intersection. In the present paper, characterizations of hyperconnected spaces using semi-preopen sets and almost feebly continuous functions are obtained. It is also shown that hyperconnectedness is preserved under surjective almost feebly continuous functions.
