Computing Orbits of Minimal Parabolic k-subgroups Acting on Symmetric k-varieties
The orbits of a minimal parabolic k-subgroup acting on a symmetric k-variety are essential to the study of symmetric k-varieties and their representations. This paper gives an algo...

Minimal symmetric Darlington synthesis
We consider the symmetric Darlington synthesis of a p × p rational symmetric Schur function S with the constraint that the extension is of size 2p×2p. Under the assumption that S...

A Centrally Symmetric Version of the Cyclic Polytope
We define a centrally symmetric analogue of the cyclic polytope and study its facial structure. We conjecture that our polytopes provide asymptotically the largest number of faces...

Detecting internally symmetric protein structures
Background: Many functional proteins have a symmetric structure. Most of these are multimeric complexes, which are made of non-symmetric monomers arranged in a symmetric manner. H...

Symmetry and performance in consistency protocols
A consistency protocol can be termed symmetric if all processors are treated identically when they access common resources. By contrast, asymmetric protocols usually assign a home...

Shape Reconstruction of 3D Bilaterally Symmetric Surfaces
The paper presents a new approach for shape recovery based on integratinggeometric and photometric information. We consider 3D bilaterally symmetric objects, that is, objects which...

Regular symmetric arrays for non-symmetric functions
A new class of non-totally symmetric functions which can be represented as simple regular symmetric arrays without redundancy is identified. Regular circuits are becoming crucialy...

Symmetric Monotone Venn Diagrams with Seven Curves
An n-Venn diagram consists of n curves drawn in the plane in such a way that each of the 2n possible intersections of the interiors and exteriors of the curves forms a connected no...

Symmetric Relations and Cardinality-Bounded Multisets in Database Systems
In a binary symmetric relationship, A is related to B if and only if B is related to A. Symmetric relationships between k participating entities can be represented as multisets of...
