Irregularity and Gevrey Index Theorems for Linear Differential Operators,and value of the irregularity follow. An application to the Maillet-Ramis theorem which makes explicit the Gevrey order of solutions of linear ordinary differential equations is included. We also sketch a method based on wild analytic continuation, that is, continuation in the infinitesimal neighborhood.

We end the chapter with the Cauchy-Heine theorem which links (non zero) asymptotic expansions to flat functions, considering both the case of Poincaré and Gevrey asymptotics.
