11. Then we expect the new eigenvalues and eigenvectors to be similar to the original, plus small perturbations : 12. In turn, they argue that small perturbations in the food supply are highly amplified for malnourished populations. 13. Now, in dual way with respect to the small perturbations , we have to solve the Schr�dinger equation 14. A small perturbation can have far-reaching results. 15. There are cases where robustness is sought against small perturbations in a nominal value of a parameter. 16. And the velocity field is modified by adding to V0 ( x, t ) a small perturbation . 17. The result of positive feedback is to augment changes, so that small perturbations may result in big changes. 18. Thus, for small eigenvalues, even small perturbations in the data can lead to considerable changes in the solution. 19. :Stability means decay of small perturbations . 20. A small perturbation is enough to let the World economy crash, because the economy has been mismanaged anyway.
