On the one hand, we need to have u0 0 (s j) = 0, for consistency with the characteristic equation at (x(s j),t(s j)). On the other, when a characteristic crosses the initial line (x(s),t(s)) twice, we would need to have the same value of u

In mathematics, the method of characteristics is a technique for solving partial differential equations. Typically, it applies to first-order equations, although more generally the method of characteristics is valid for any hyperbolic partial differential equation. The method is to reduce a partial differential equation … See more For a first-order PDE (partial differential equation), the method of characteristics discovers curves (called characteristic curves or just characteristics) along which the PDE becomes an ordinary differential equation (ODE). … See more Characteristics are also a powerful tool for gaining qualitative insight into a PDE.
