We know that Kolmogorov Cmplexity (KC) has connections to mathematical logic since it can be used to prove the Gödel incompleteness results (Chaitin's Theorem and [Kritchman-Raz][1]). Are there any other striking application of Kolmogorov complexity to mathematical logic (outside KC itself of course)? Relatively simple examples like the ones I mentioned are preferred, but more complicated illustrations are also very welcome!
