New classes $R_1$, $R_2$, $R_3$ of topological spaces generalizing the class of $F$-spaces are introduced. It is proved that all homogeneous compact subspaces of spaces in these classes and of some of their products are finite. Results on the Rudin–Keisler comparability of ultrafilters along which distinct sequences converge to the same point in $R_2$- and $R_3$-spaces are obtained.
