Applying Homotopy to Surface-Surface Intersections
نویسنده
چکیده
Homotopy is a method for finding the roots of one equation by slowly transforming an equation to which the roots are known into the equation of interest, keeping track of how the roots change as the equation does. Homotopy has been considered in the past for surface-surface intersections in computer-aided geometric design, but rejected out of concern for speed or numerical accuracy. However, recent developments in the field as well as faster computers make this algorithm a viable candidate. Particularly, homotopy should be useful in finding starting points for tracing the intersection curve of two implicit surfaces.

Statistics of Intersections of Curves on Surfaces
Each orientable surface with nonempty boundary can be associated with a planar model, whose edges can then be labeled with letters that read out a surface word. Then, the curve word of a free homotopy class of closed curves on a surface is the minimal sequence of edges of the planar model through which a curve in the class passes. The length of a class of curves is defined to be the number of l...
متن کاملVirtual Strings and Their Cobordisms
A virtual string is a scheme of self-intersections of a closed curve on a surface. We study algebraic invariants of strings as well as two equivalence relations on the set of strings: homotopy and cobordism. We show that the homotopy invariants of strings form an infinite dimensional Lie group. We also discuss connections between virtual strings and virtual knots.

متن کاملOn the convergence of the homotopy analysis method to solve the system of partial differential equations
One of the efficient and powerful schemes to solve linear and nonlinear equations is homotopy analysis method (HAM). In this work, we obtain the approximate solution of a system of partial differential equations (PDEs) by means of HAM. For this purpose, we develop the concept of HAM for a system of PDEs as a matrix form. Then, we prove the convergence theorem and apply the proposed method to fi...
متن کاملLeast Area Incompressible Surfaces in 3-Manifolds
Let M be a Riemannian manifold and let F be a closed surface. A map f: F---,M is called least area if the area of f is less than the area of any homotopic map from F to M. Note that least area maps are always minimal surfaces, but that in general minimal surfaces are not least area as they represent only local stationary points for the area function. The existence of least area immersions in a ...
