Enriched Riemann Sphere, Morse Stability and Equi-singularity in mathcal{O}₂

The \textit{Enriched Riemann Sphere} $\C P_*^1$ is $\C P^1$ plus a set of \textit{infinitesimals}, having the Newton-Puiseux field $\F$ as coordinates. Complex Analysis is extended to the $\F$-\textit{Analysis} (\textit{Newton-Puiseux Analysis}). The classical \textit{Morse Stability Theorem} is also extended; the \textit{stability idea} is used to formulate an \textit{equi-singular deformation theorem} in $\C\{x,y\}(=\mathcal{O}_2)$.
