Error estimate of a first-order time discretization scheme for the geodynamo equations

A Discretization Scheme and Error Estimate for First-order Systems and Elliptic Problems

A discretization scheme applicable to the direct approximation of the velocity variable for either a rst-order system or second-order elliptic equation is proposed in this paper. The scheme is motivated by mixed nite element methods and extends the cell-centered nite diierence and the nite volume element methods to problems with discontinuous coeecients and various boundary conditions. Error es...

Improved discretization error estimates for first-order system least squares

We study the discretization accuracy for first-order system least squares (FOSLS) applied to Poisson’s equation as a model problem. The FOSLS formulation is based on an H1 elliptic bilinear form F . Since the order of convergence of the discretization in the L2 and H1 norms depends on the regularity of F , we examine this property in detail. We then use these results together with an Aubin-Nits...

First order linear fuzzy dynamic equations on time scales

In this paper, we study the concept of generalized differentiability for fuzzy-valued functions on time scales. Usingthe derivative of the product of two functions, we provide solutions to first order linear fuzzy dynamic equations. Wepresent some examples to illustrate our results.
