If you have a question about this talk, please contact Andrew Thomason. By a “permutation”, we just mean the elements {1..N} written out in some order. Suppose we take two of these at random, and add them together pointwise, modulo N. What is the probability that the resulting sequence is again a permutation? This question has been posed in the literature under various guises, and a number of bounds proven or conjectured. In recent work with Sean Eberhard and Rudi Mrazovic, we compute the answer up to a factor of 1 + o(1). I will outline the proof, which uses Fourier analysis and some methods from analytic combinatorics.
