6 – Other Problems

In this chapter, we will continue to consider the spatial domain of problem (P 0 ) P 0 , which is the cylinder Ω=]0,a[×O Ω = ] 0 , a [ × O in ℝ n . This will allow us to formulate spatial invariant embedding more simply, but we also wish to show that the factorization method may be extended to other classical types of linear elliptic equations. At the end of the chapter, we will discuss parabolic problems.
