Differential geometric computations and computer algebra
Mathematical and Computer Modelling, 1997 The authors discuss the use of computer algebra (CA) in the field of differential geometry (DG) and its applications to geometric structures of partial differential equations. A number of CA packages allow to do DG computations: computations for differential forms and vector fields, such as differentiation, inner products, Lie derivatives, and so on ...

Progressive geometric algorithms
Journal of Computational Geometry, 2015 Progressive algorithms are algorithms that, on the way to computing a complete solution to the problem at hand, output intermediate solutions that approximate the complete solution increasingly well.

Observation of Entanglement-Dependent Two-Particle Holonomic Phase [PDF]
, 2014 Holonomic phases---geometric and topological---have long been an intriguing aspect of physics. They are ubiquitous, ranging from observations in particle physics to applications in fault tolerant quantum computing. However, their exploration in particles

Abstract geometrical computation 7: geometrical accumulations and computably enumerable real numbers [PDF]
Natural Computing, 2012 Using rules to automatically extend a drawing on an Euclidean space might lead to accumulating drawings into a single point. Such points are characterized in the context of Abstract geometrical computation. Colored line segments (traces of signals) are drawn according to rules: signals with similar color are parallel and when they intersect, they are ...

Area collapse algorithm computing new curve of 2D geometric objects
Geodesy and Cartography, 2017 The processing of cartographic data demands human involvement. Up-to-date algorithms try to automate a part of this process. The goal is to obtain a digital model, or additional information about shape and topology of input geometric objects.

Ground-state geometric quantum computing in superconducting systems
, 2010 We present a theoretical proposal for the implementation of geometric quantum computing based on a Hamiltonian which has a doubly degenerate ground state. Thus the system which is steered adiabatically, remains in the ground-state.

Geometric phases and quantum computations [PDF]
Physics Letters A, 2002 Calculation aspects of holonomic quantum computer (HQC) are considered. Wilczek--Zee potential defining the set of quantum calculations for HQC is explicitly evaluated. Principal possibility of realization of the logical gates for this case is discussed.
