Reflect the shape in the line \(x = -1\). The line \(x = -1\) is a vertical line which passes through -1 on the \(x\)-axis. The line \(y = 1\) is a horizontal line which passes through 1 on the ...

SIAM Journal on Numerical Analysis, Vol. 36, No. 3 (Mar. - May, 1999), pp. 935-952 (18 pages) A family of explicit space-time finite element methods for the initial boundary value problem for linear, ...

The Tricomi equation can be expressed in symmetric positive form. Admissible boundary conditions assure existence and uniqueness of solutions. In this paper it is shown what boundary conditions are ...

The Einstein field equations are a system of second order, non-linear, coupled differential equations in 4 variables. As you can imagine, solving such a system is not easy. If the system possesses a ...
