On f-invariant and attractive affine varieties for continuous-time polynomial systems: The case of robot motion planning

53rd IEEE Conference on Decision and Control, 2014
The main objective of this paper is to describe a class of polynomial vector fields f, whose associated dynamic system has one or more affine varieties as f-invariant and attractive sets. This result can be used for robot motion planning, thus computing robot paths, avoiding collisions with obstacles and reaching a target point.

The affine index polynomial invariant of flat virtual knots

Journal of Knot Theory and Its Ramifications, 2014
We define the affine index polynomial of a flat virtual knot in a similar way as the case of a virtual knot, and show that it is described by the affine index polynomial of any overlying virtual knot. Let K be a virtual knot, and F the underlying flat virtual knot of K.

An affine index polynomial invariant and the forbidden move of virtual knots

Journal of Knot Theory and Its Ramifications, 2016
Kauffman defines an affine index polynomial invariant for virtual knots. The invariant is induced from a numerical invariant called an [Formula: see text]-writhe. In this paper, we provide the difference of the values obtained from invariants between two virtual knots which can be transformed into each other by a single forbidden move. As a result, we
