The Wave Equation,e promised not to use distribution theory, we will make no attempt to prove the solution formulas in the most general context. It is understood that the functions we manipulate are supposed to allow the formula to be defined in the classical sense.

Variable Coefficient Wave Equations and Systems,would like . to be an operator similar to the wave operator, and to enjoy the same properties: Finite speed of propagation, energy inequalities, etc. We saw in . that, for an operator in the plane, it is natural to require that its principal part should be the principal part of a product a real vect

The most striking asymmetries are present approximately on the level of 5. ribs, where the postoperative scar is also the mos
