Linearly implicit methods for Allen-Cahn equation
, 2023 It is well known that the Allen-Cahn equation satisfies a nonlinear stability property, i.e., the free-energy functional decreases in time. Linearly implicit integrators have been developed for energy-preserving methods for conservative systems with ...

Implicitization of rational parametric equations
Journal of Symbolic Computation, 1992 The paper adresses the implicitization problem for rational parametric equations and presents algorithms based on the Gröbner basis method. The authors give methods: to compute a basis of the implicit ideal for a set of rational parametric equations; to reparametrize a set of parametric equations so that the parameters of the new parametric 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 ...

Numerical Solution of a Kind of Fractional Parabolic Equations via Two Difference Schemes
Abstract and Applied Analysis, 2013 A kind of parabolic equation was extended to the concept of fractional calculus. The resulting equation is, however, difficult to handle analytically. Therefore, we presented the numerical solution via the explicit and the implicit schemes.
