Compact Sets without Converging Sequences in the Random Real Model
A. Dow and D. Fremlin


Abstract.  It is shown that in the model obtained by adding any number of random reals to a model of CH, there is a compact Hausdorff space of weight w1 which contains no non-trivial converging sequences. It is shown that for certain spaces with no converging sequences, the addition of random reals will not add any converging sequences.

Keywords:  random reals, converging sequences, Efimov problem.
