Introduction to differential equations. Topics include methods of solutions for linear and non-linear first order differential equations, linear second order differential equations, higher order ...

First Order Systems First Order Systems First-order systems are those which can be described by first-order differential equations. A common example is the RC circuit. You will need Adobe Acrobat ...

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