Simple permutations mix even better
We study the random composition of a small family of O(n3 ) simple permutations on {0, 1}n . Specifically we ask how many randomly selected simple permutations need be composed to...

Delayed path coupling and generating random permutations
We analyze various stochastic processes for generating permutations almost uniformly at random in distributed and parallel systems. All our protocols are simple, elegant and are b...

Longest Increasing Subsequences in Pattern-Restricted Permutations
Inspired by the results of Baik, Deift and Johansson on the limiting distribution of the lengths of the longest increasing subsequences in random permutations, we find those limit...

Longest Alternating Subsequences in Pattern-Restricted Permutations
We determine the limiting distributions of the longest alternating subsequence for pattern-restricted permutations in which the pattern is any one of the six patterns of length th...

Analysis of Countermeasures Against Access Driven Cache Attacks on AES
Cache attacks on implementations of cryptographic algorithms have turned out to be very powerful. Progress in processor design, e.g., like hyperthreading, requires to adapt models ...
