The construction of final coalgebras in Set is mysterious. In general the construction involves
a universal quotient in the super-large category of classes not in Set. With the cardinality
condition, the question is still not simple.
However, with topology the construction becomes simpler. By applying Stone duality, the
construction of final coalgebras in topological spaces is equivalent to the construction of initial
algebras in the category of open sets, i.e. frames (with mild conditions). This approach gives
a simpler way to calculate and provides applications in coalgebraic logic and domain theory.
