Zusammenfassung

The RAM complexity of deterministic linear space sorting of integers in words is improved from $O(n\sqrt{\log n})$ to $O(n(\log\log n)^2)$. No better bounds are known for polynomial space. In fact, the techniques give a deterministic linear space priority queue supporting insert and delete in $O((\log\log n)^2)$ amortized time and find-min in constant time. The priority queue can be implemented using addition, shift, and bit-wise boolean operations.
