On singularity confinement for the pentagram map [PDF]
Discrete Mathematics & Theoretical Computer Science, 2012 The pentagram map, introduced by R. Schwartz, is a birational map on the configuration space of polygons in the projective plane. We study the singularities of the iterates of the pentagram map.

Architectural singularities of parallel mechanisms with prismatic joints due to special designs of platform shapes [PDF]
Mechanical Sciences, 2019 Singularity is an inherent property of robotic manipulators. A manipulator becomes singular when it gains or losses degrees of freedom at a particular configuration.

Electronic Journal of Qualitative Theory of Differential Equations, 2014 In this article we obtain the geometric classification of singularities, finite and infinite, for the three subclasses of quadratic differential systems with $m_f=4$ possessing exactly two finite singularities, namely: (i) systems with two double complex

Kinematics and Singularity Analysis of a 7-DOF Redundant Manipulator
Sensors, 2021 A new method of kinematic analysis and singularity analysis is proposed for a 7-DOF redundant manipulator with three consecutive parallel axes. First, the redundancy angle is described according to the self-motion characteristics of the manipulator, the ...

Workspace and Singularity analysis of a Delta like family robot [PDF]
, 2015 Workspace and joint space analysis are essential steps in describing the task and designing the control loop of the robot, respectively. This paper presents the descriptive analysis of a family of delta-like parallel robots by using algebraic tools to ...

Generic singular configurations of linkages
Topology and its Applications, 2012 We study the topological and differentiable singularities of the configuration space C( ) of a mechanical linkage in d-dimensional Euclidean space, defining an inductive sufficient condition to determine when a configuration is singular. We show that this condition holds for generic singularities, provide a mechanical interpretation, and give an ...

Solvable Groups, Free Divisors and Nonisolated Matrix Singularities II: Vanishing Topology [PDF]
, 2013 In this paper we use the results from the first part to compute the vanishing topology for matrix singularities based on certain spaces of matrices. We place the variety of singular matrices in a geometric configuration of free divisors which are the ...

Taming triangulation dependence of T 6/ℤ2 × ℤ2 resolutions
Journal of High Energy Physics, 2022 Resolutions of certain toroidal orbifolds, like T 6/ℤ2 × ℤ2, are far from unique, due to triangulation dependence of their resolved local singularities. This leads to an explosion of the number of topologically distinct smooth geometries associated to a ...

Cosmology and Fermion Confinement in a Scalar-Field-Generated Domain Wall Brane in Five Dimensions [PDF]
, 2006 We consider a brane generated by a scalar field domain wall configuration in 4+1 dimensions, interpolating, in most cases, between two vacua of the field.
