There is no general reliable procedure to solve nonlinear ODEs, but some methods have been proposed. Partial di erential equations (PDEs) NISQ [GRG22], FTol Theo [CLO21; Kro22], QIns [Gar21]. In general, plasma systems are described by partial di erential equations. Although some of the equations presented here do not commonly describe plasma systems, the techniques employed to solve them are often general enough that they could be adapted to tackle plasma PDEs. For ease of search, PDEs arising from stochastic processes are indicated both here and in the following section.
