Critical Points at Infinity: a missing link in vector field topology
نویسندگان
چکیده
This paper presents an improved technique for extracting singular streamlines that extends the capabilities of vector field topology. Singular streamlines are a unique set of tangent curves that connect singular or critical points. In prior work [Ken99], we demonstrated that vector field topology (a well-known technique for extracting singular streamlines) failed to identify a class of singular streamlines because they did not originate from critical points inside the computational domain. In this paper, we show that singular streamlines that originate from critical points at infinity are the missing link and account for the previously undetectable “open” singular streamlines.

Monodromy problem for the degenerate critical points
For the polynomial planar vector fields with a hyperbolic or nilpotent critical point at the origin, the monodromy problem has been solved, but for the strongly degenerate critical points this problem is still open. When the critical point is monodromic, the stability problem or the center- focus problem is an open problem too. In this paper we will consider the polynomial planar vector fields ...
متن کاملFinite Time Steady Vector Field Topology - Theoretical Foundation and 3D Case -
Vector Field Topology is the standard approach for the analysis of asymptotic particle behavior in a vector field flow: A topological skeleton is separating the flow into regions by the movement of massless particles for an integration time converging to infinity. In some use cases however only a finite integration time is feasible. To this end, the idea of a topological skeleton with an augmen...
متن کاملCurvature Measures of 3D Vector Fields and their Applications
Tangent curves are a powerful tool for analyzing and visualizing vector fields. In this paper two of their most important properties are examined: their curvature and torsion. Furthermore, the concept of normal surfaces is introduced to the theory of 3D vector fields, and their Gaussian and mean curvature are analyzed. It is shown that those four curvature measures tend to infinity near critica...
متن کاملTracking Closed Streamlines in Time Dependent Planar Flows
Closed streamlines are a missing part in most visualizations of vector field topology. In this paper, we propose a method which detects closed streamlines in a time-dependent two-dimensional flow and investigates the behavior of these closed streamlines over time. We search in all timesteps for closed streamlines and connect them to each other in temporal order to get a tube shaped visualizatio...
متن کاملOn the topology of semi-algebraic functions on closed semi-algebraic sets
We consider a closed semi-algebraic set X ⊂ R and a C semi-algebraic function f : R → R such that f|X has a finite number of critical points. We relate the topology of X to the topology of the sets {f ∗ α}, where ∗ ∈ {≤,=,≥} and α ∈ R, and the indices of the critical points of f|X and −f|X . We also relate the topology of X to the topology of the links at infinity of the sets {f ∗ α} and the in...
