Radical parametrizations of algebraic curves by adjoint curves
Journal of Symbolic Computation, 2011 We present algorithms for parametrizing by radicals an irreducible curve, not necessarily plane, when the genus is less o equal to 4 and they are defined over an algebraically closed field of characteristic zero. In addition, we also present an algorithm for parametrizing by radicals any irreducible plane curve of degree $d$ having at least a point of ...

Parametric Manifolds I: Extrinsic Approach [PDF]
, 1994 A parametric manifold can be viewed as the manifold of orbits of a (regular) foliation of a manifold by means of a family of curves. If the foliation is hypersurface orthogonal, the parametric manifold is equivalent to the 1-parameter family of ...

Effects of the core radius of an isothermal ellipsoidal gravitational lens on the caustics and the critical curves [PDF]
, 2004 We study the effect of the core radius of an isothermal ellipsoidal gravitational lens on the caustics and the critical curves. We derive an analytic expression of the caustics for an isothermal ellipsoidal gravitational lens via a sixth-order algebraic ...

Constructing parametric quadratic curves
Journal of Computational and Applied Mathematics, 1999 Constructing a parametric spline curve to pass through a set of data points requires assigning a knot to each data point. In this paper the authors discuss the construction of parametric quadratic splines and present a new method to assign knots to a set of planar data points.

Catchments do not strictly follow Budyko curves over multiple decades, but deviations are minor and predictable [PDF]
Hydrology and Earth System SciencesQuantification of precipitation partitioning into evaporation and runoff is crucial for predicting future water availability. Within the widely used Budyko framework, which relates the long-term aridity index to the long-term evaporative index ...

Parametric Hull Design with Rational Bézier Curves and Estimation of Performances
Journal of Marine Science and Engineering, 2021 In this paper, a tool able to support the sailing yacht designer during the early stage of the design process has been developed. Cubic Rational Bézier curves have been selected to describe the main curves defining the hull of a sailing yacht.

Biharmonic Curves in a Strict Walker 3-Manifold
International Journal of Mathematics and Mathematical Sciences, 2022 In this paper, we study the geometry of biharmonic curves in a strict Walker 3-manifold and we obtain explicit parametric equations for biharmonic curves and time-like biharmonic curves, respectively.

On the duality between p-Modulus and probability measures [PDF]
, 2014 Motivated by recent developments on calculus in metric measure spaces $(X,\mathsf d,\mathfrak m)$, we prove a general duality principle between Fuglede's notion of $p$-modulus for families of finite Borel measures in $(X,\mathsf d)$ and probability ...
