The implicit equation of a canal surface
Journal of Symbolic Computation, 2009 A canal surface is an envelope of a one parameter family of spheres. In this paper we present an efficient algorithm for computing the implicit equation of a canal surface generated by a rational family of spheres. By using Laguerre and Lie geometries, we relate the equation of the canal surface to the equation of a dual variety of a certain curve in 5-

Stability of Nonlinear Implicit Differential Equations with Caputo–Katugampola Fractional Derivative
, 2023 The purpose of this paper is to study nonlinear implicit differential equations with the Caputo–Katugampola fractional derivative. By using Gronwall inequality and Banach fixed-point theorem, the existence of the solution of the implicit equation ...

Feedback linearization of discrete-time nonlinear control systems: computational aspects [PDF]
Proceedings of the Estonian Academy of Sciences, 2020 An alternative solution of the static state feedback linearization problem for the discrete-time case is given. This solution is based on the sequence of distributions, whose computation requires only the knowledge of the backward shift equations.

On Discontinuous Implicit Evolution Equations
Journal of Mathematical Analysis and Applications, 1998 Let \(J\) be an interval of the form \([0,T]\) of the real line. The paper deals with an IVP of the form \[ f(t,u(t), Lu(t))= 0,\tag{\(*\)} \] for a.e. \(t\in J\), \(u(0)= u_0\). Here, \(u\) is a function on \(J\) to an ordered \(B\)-space \(E\), \(L\) is a differential-like operator with values in \(L^p(J,E)\) and \(f\) satisfies some monotonicity ...

Desingularization of implicit analytic differential equations [PDF]
Journal of Physics A: Mathematical and General, 2006 The question of finding solutions to given implicit differential equations (IDE) has been answered by several authors in the last few years, using different approaches, in an algebraic and also a geometric setting. Many of those results assume in one way or another that the subimmersion theorem can be applied at several stages of the reduction ...

FVM 1.0: a nonhydrostatic finite-volume dynamical core for the IFS [PDF]
Geoscientific Model Development, 2019 We present a nonhydrostatic finite-volume global atmospheric model formulation for numerical weather prediction with the Integrated Forecasting System (IFS) at ECMWF and compare it to the established operational spectral-transform formulation.

Numerical solutions for implicit differential equations with singularities
Semina: Ciências Exatas e Tecnológicas, 2022 In this paper we introduce a technique to deal with implicit differential equations exhibiting singularities. Our approach is a geometrical one, we use the concept of contact structure on a manifold associated with the differential equation.
