On Dynamic Subset Difference Revocation Scheme
Subset Difference Revocation (SDR) [8] has been proposed to perform group rekeying in a stateless manner. However, statelessness comes at a cost in terms of storage and message ove...

On the Number of Graphical Forest Partitions
A graphical partition of the even integer n is a partition of n where each part of the partition is the degree of a vertex in a simple graph and the degree sum of the graph is n. ...

Subdomain Aware Contour Trees and Contour Evolution in Time-Dependent Scalar Fields
For time-dependent scalar fields, one is often interested in topology changes of contours in time. In this paper, we focus on describing how contours split and merge over a certa...

A Topological Constraint Language with Component Counting
A topological constraint language is a formal language whose variables range over certain subsets of topological spaces, and whose nonlogical primitives are interpreted as topologi...

Counting Inversions, Offline Orthogonal Range Counting, and Related Problems
We give an O(n lg n)-time algorithm for counting the number of inversions in a permutation on n elements. This improves a long-standing previous bound of O(n lg n/ lg lg n) that ...
