AGONY

Hyperbolic equations in higher dimensions,erator “□” defined by (1.1) is known as the .. For .=3 the equation can represent waves in acoustics or optics, for .=2 waves on the surface of water, for .=1 sound waves in pipes or vibrations of strings. In the initial-value problem we ask for a solution of (1.1) defined in the (.+1)-dimensional half space .>0 for which

acheon

Higher-order elliptic equations with constant coefficients,lves to a single linear homogeneous .th-order equation with constant real coefficients for a scalar function .(.)=.(.,...,.). We write the equation in the familiar form . where . is an .th-degree form in .=(.,...,.) with constant real coefficients .. Equation (0.1) is . (see p. 58), if there are no real characteristic surfaces, that is, if

貧窮地活

Parabolic equations,erature in a heat-conducting medium. For .=1 it holds for the temperature distribution in a heat-conducting insulated wire. The same type of equation occurs in the description of diffusion processes. Applying a suitable linear substitution on . we transform (1.1) into . which will be used in the discussion to follow.

神圣在玷污

The Laplace equation,The . acting on a function .(.) = .(.,...,.) of class . in a region Ω is defined by . For . we have (see Chapter 3, (4.8), (4.9)) Green’s identities. . where . indicates differentiation in the direction of . normal to ?Ω.
