Hyperbolic Equations,n the simplest case of the wave equation in two independent variables* . it is easily seen that the maximum of a nonconstant solution . in a domain . may occur at an interior point. For example, we observe that the function . satisfies the above equation, and that it attains its maximum in the square 0 < . < ., 0 < . < ., at the center (./2, ./2).
