Special Criteria for Inverse Stability
In this chapter, we analyze special criteria which guarantee for linear problems the inverse stability inequalities established in Chapter 11. These criteria strongly depend on the norms of the approximating spaces. The significance of the choice of norms was already made clear in Section 11.1 where we verified the differentiability requirements for several classes of examples. The analysis in this chapter, moreover, is applicable to nonlinear problems. Indeed, we know that the inverse stability of a nonlinear sequence of differentiable mappings is guaranteed whenever the associated sequence of Fréchet-derivatives is inversely stable.
