Characterization of rank two locally nilpotent derivations in dimension three (2007)
Barkatou, Moulay A., Houari, Hassan El, Kahoui, M'hammed El
In this paper we give an algorithmic characterization of rank two locally nilpotent derivations in dimension three. Together with an algorithm for computing the plinth ideal, this gives a method for...
Triangulable locally nilpotent derivations in dimension three (2007)
Barkatou, Moulay A., Houari, Hassan El, Kahoui, M'hammed El
In this paper we give an algorithm to recognize triangulable locally nilpotent derivations in dimension three. In case the given derivation is triangulable, our method produces a coordinate system in...
