For close to fifty years, the territorial dispute between Nigeria and Cameroon continued over the region along their border known as the Bakassi peninsula. The dispute almost led to war in the mid-1990s, was settled by the International Court of Justice in 2002, and resulted in hand-off of the territory by Nigeria to Cameroon in 2008.

Antarctica is a continent on the brink. The constant political instability of oilrich nations, coupled with an increasing global petroleum demand, is fueling the likelihood that the world will turn its thirsty eyes towards this great unexplored frontier in search of natural energy resources. Mineral exploration in Antarctica, however, has been effectively barred since 1959 under the Antarctic T...

We study some structural and topological properties of the frontiers of objects in a certain class of discrete spaces, in the framework of simplicial complexes and partial orders. In a previous work, we introduced the notion of frontier order, which allows to define the frontier of any object in an n-dimensional space. The main goal of this paper is to exhibit the links which exist between fron...

We present a new spatial partitioning scheme called frontier sets. Frontier sets build on the notion of a potentially visible set (PVS) [ARB90, TS91]. In a PVS a world is sub-divided into cells and for each cell all the other cells that can be seen are computed. Frontier sets represents regions of mutual invisibility. One frontier in a frontier set considers pairs of cells, A and B. It lists tw...
