	abstract = {Using the notions of Q-heaps and fusion trees developed by Fredman andWillard, we develop a faster version of the fractional cascading technique
while maintaining the linear space structure. The new version enables
sublogarithmic iterative search in the case when we have a search tree and
the degree of each node is bounded by $O(\log^{\epsilon}n)$, for some
constant $\epsilon >0$, where $n$ is the total size of all the lists
stored in the tree. The fast fractional cascading technique is used in
combination with other techniques to derive sublogarithmic time algorithms
for the geometric retrieval problems: orthogonal segment intersection and
rectangular point enclosure. The new algorithms use $O(n)$ space and
achieve a query time of $O(\log n/\log\log n + f)$, where $f$ is the number of objects satisfying the query. All our algorithms assume the
version of the RAM model used by Fredman and Willard.
