Internal and External History of Science,In principle, in this chapter, we will study the wave equation, which constitutes the prototype of the hyperbolic equations. Let . be an open set from . and . a real number .. Then, the Cauchy problem, associated with the wave equation, consists of .where . is the notation for the cylinder ..
