چکیده
Anthropologists have extensively examined the material politics of bureaucratic rule and technical expertise. But ethnographic analysis must also attend to mathematical abstractions that cannot be reduced any specific kind materiality. A key site appreciate such is georeferentiation Indigenous property polygons in Peru's Amazonian region Loreto. In context climate change biodiversity loss, both Peruvian state communities pinned their hopes on mathematically stabilizing polygons. these are haunted by confusing accumulations informal attempts make sense territories over time. To accumulations, engineer (ingeniero) can serve as a privileged prism. Thinking through provides an opportunity interrogate emerging forms territoriality Amazonia, well contentious contemporary global environmental governance.

Dissections of Polygons into Convex Polygons
In the paper we present purely combinatorial conditions that allow us to recognize the topological equivalence (or non-equivalence) of two given dissections. Using a computer program based on this result, we are able to generate a set which contains all topologically non-equivalent dissections of a p0-gon into convex pi-gons, i = 1, ..., n, where n, p0, ..., pn are integers such that n ≥ 2, pi ...
متن کاملGuarding Fat Polygons and Triangulating Guarded Polygons
In this paper we study three related problems: (i) Given a fat polygon P , we show how to find a set G of points in P such that every point on the boundary of P sees at least one point of G. The set G is said to guard the boundary of P and its cardinality depends on the shape parameters of P . Fat polygons are often used to model more realistic inputs. (ii) Given k points that guard the boundar...
متن کاملConvexity of Sub-polygons of Convex Polygons
A convex polygon is defined as a sequence (V0, . . . , Vn−1) of points on a plane such that the union of the edges [V0, V1], . . . , [Vn−2, Vn−1], [Vn−1, V0] coincides with the boundary of the convex hull of the set of vertices {V0, . . . , Vn−1}. It is proved that all sub-polygons of any convex polygon with distinct vertices are convex. It is also proved that, if all sub-(n − 1)-gons of an n-g...
متن کاملSpecial Polygons
(1) For all real numbers r1, r2, r′ 1, r ′ 2 such that [r1,r2] = [r ′ 1,r ′ 2] holds r1 = r ′ 1 and r2 = r ′ 2. (2) If i+ j = len f , then L( f , i) = L(Rev( f ), j). (3) If i+1 ≤ len( f n), then L( f n, i) = L( f , i). (4) If n ≤ len f and 1 ≤ i, then L( f n, i) = L( f ,n+ i). (5) If 1 ≤ i and i+1 ≤ len f −n, then L( f n, i) = L( f ,n+ i). (6) If i+1 ≤ len f , then L( f a g, i) = L( f , i). (7...
متن کاملFlipturning polygons
A central problem in polymer physics and molecular biology is the reconfiguration of large molecules (modeled as polygons) such as circular DNA. Most of the research in this area involves computer-intensive Monte-Carlo simulations. One efficient method frequently used to generate random chains or polygons is to modify one such object into another using a simple pivot operation. This paper is co...
