On projective plane curve evolution
نویسندگان
چکیده
In this paper, we investigate the evolution of curves of the projective plane according to a family of projective invariant intrinsic equations. This is motivated by previous work for the Euclidean 9, 10, 13] and the aane cases 19, 20, 3, 2] as well as by applications in the perception of two-dimensional shapes. We establish the evolution laws for the projective arclength and curvature. Among this family of equations, we deene a \projective heat equation" 6] and establish the link with the projective evolution of curves in R 2 .

Some recent results on the projective evolution of 2-D curves
In this paper, we begin to explore the evolution of curves of the projective plane according to a family of intrinsic equations generalizing a projective heat equationn 1]. This is motivated by previous work for the Euclidean 2, 3, 4] and the aane case 5, 6, 7, 8] as well as by applications in the perception of two-dimensional shapes. We establish the projective arclength evolution and the proj...
متن کاملSymmetric Plane Curves of Degree 7 : Pseudoholomorphic and Algebraic Classifications
This paper is motivated by the real symplectic isotopy problem : does there exist a nonsingular real pseudoholomorphic curve not isotopic in the projective plane to any real algebraic curve of the same degree? Here, we focus our study on symmetric real curves on the projective plane. We give a classification of real schemes (resp. complex schemes) realizable by symmetric real curves of degree 7...
متن کاملSmooth Projective Planes
Using symplectic topology and the Radon transform, we prove that smooth 4-dimensional projective planes are diffeomorphic to CP. We define the notion of a plane curve in a smooth projective plane, show that plane curves in high dimensional regular planes are lines, prove that homeomorphisms preserving plane curves are smooth collineations, and prove a variety of results analogous to the theory ...
متن کاملPseudo-holomorphic and Algebraic Classifications
Almost all known restrictions on the topology of nonsingular real algebraic curves in the projective plane are also valid for a wider class of objects: real pseudo-holomorphic curves. It is still unknown if there exists a nonsingular real pseudo-holomorphic curve not isotopic in the projective plane to a real algebraic curve of the same degree. In this article, we focus our study on symmetric r...
متن کاملRokhlin’s Formula for Dividing T-Curves
A nonsingular real algebraic plane projective curve is called a dividing curve or a curve of type I if its real point set divides its complex point set. Rokhlin’s formula, which holds for such curves, is an important step in order to classify nonsingular real algebraic plane projective curves. It gives prohibitions on the complex orientations of a curve of type I and also on its real scheme. Th...
