This paper develops ellipticity estimates and discretization error bounds for elliptic equations (with lower-order terms) that are reformulated as a least-squares ...

A second-order system is one which can be described by a second-order differential equation. The files listed below are a combination of PDF tutorial documents, MATLAB Graphical User Interfaces (GUIs) ...

A tersely annotated collection of references on types of approaches used in currently available methods to solve the general linear, first-order ordinary differential equation is presented, and ...
