Arf Invariants of Real Algebraic Curves
. Let CA be the complex curve in CP(2) given by the same polynomial as RA. Thus RA = CA∩RP(2). RA is a M-curve precisely when CA \ RA consists of two punctured spheres which are interchanged by complex conjugation. Arbitrarily choose one of these components, say CA. The complex structure on CA induces an orientation on CA, and thus on each immersed circle of RA. Of course if we choose the other...
متن کاملNoncommutative invariants of algebraic curves
We prove that an algebraic curve of genus g admits a representation by the interval exchange transformation. This representation is based on the “zippered rectangles” technique due to W. Veech. The invariants Oλ and θλ of the interval exchange transformation are shown to be the projective invariants of the curve C. We establish a Riemann–Roch formula for Oλ. The first steps to the classificatio...
متن کاملInvariants for Tactile Recognition of Algebraic Curves
In this paper we study the recognition of low-degree polynomial curves based on minimal tactile data. Euclidean differential and semidifferential invariants have been derived for quadratic curves and special cubic curves that are found in applications. These invariants, independent of translation and rotation, are evaluated over the differential geometry at up to three points on a curve. Their ...
متن کاملSpinor states of real rational curves in real algebraic convex 3-manifolds and enumerative invariants
Let X be a real algebraic convex 3-manifold whose real part is equipped with a Pin− structure. We show that every irreducible real rational curve with non-empty real part has a canonical spinor state belonging to {±1}. The main result is then that the algebraic count of the number of real irreducible rational curves in a given numerical equivalence class passing through the appropriate number o...
متن کاملReal Plane Algebraic Curves
We study real algebraic plane curves, at an elementary level, using as little algebra as possible. Both cases, affine and projective, are addressed. A real curve is infinite, finite or empty according to the fact that a minimal polynomial for the curve is indefinite, semi–definite nondefinite or definite. We present a discussion about isolated points. By means of the operator, these points can ...
