On Turn-Regular Orthogonal Representations
نویسندگان
چکیده
An interesting class of orthogonal representations consists the so-called turn-regular ones, i.e., those that do not contain any pair reflex corners point to each other inside a face. For such representation H it is possible compute in linear time minimum-area drawing, drawing minimum area over all assignments vertex and bend coordinates H. In contrast, finding NP-hard if non-turn-regular. This scenario naturally motivates study which graphs admit representations. this paper we identify notable classes biconnected planar always representations, can be computed time. We also describe linear-time testing algorithm for trees provide polynomial-time tests whether plane graph with small faces has without bends.

Distinguished positive regular representations
Let $G$ be a tamely ramified reductive $p$-adic group. We study distinction of a class of irreducible admissible representations of $G$ by the group of fixed points $H$ of an involution of $G$. The representations correspond to $G$-conjugacy classes of pairs $(T,phi)$, where $T$ is a tamely ramified maximal torus of $G$ and $phi$ is a quasicharacter of $T$ whose restriction t...
متن کاملTurn-Regularity and Planar Orthogonal Drawings
Given an orthogonal representation H with n vertices and bends, we study the problem of computing a planar orthogonal drawing of H with small area. This problem has direct applications to the development of practical graph drawing techniques for information visualization and VLSI layout. In this paper, we introduce the concept of turn-regularity of an orthogonal representation H, provide combin...
متن کاملProjections of regular orthogonal arrays
In this paper, we show that the projection of a regular orthogonal array of strength t onto more than t factors consists of replicates of either a fractional factorial or a full factorial design of strength t, depending on the number of factors retained in the projection.
متن کاملǫ-Constants and Orthogonal Representations
In this paper we suppose G is a finite group acting tamely on a regular projective curve X over Z and V is an orthogonal representation of G of dimension 0 and trivial determinant. Our main result determines the sign of the ǫ-constant ǫ(X/G, V ) in terms of data associated to the archimedean place and to the crossing points of irreducible components of finite fibers of X , subject to certain st...
متن کاملOriented Lagrangian Orthogonal Matroid Representations
Several attempts have been made to extend the theory of matroids (here referred to as ordinary or classical matroids) to theories of more general objects, in particular the Coxeter matroids of Borovik, Gelfand and White ([7], first introduced as WP-matroids in [10]), and the ∆-matroids and (equivalent but for notation) symmetric matroids of Bouchet (see, for example, [8]). The special cases of ...
