Let an ODE where F is analytic in The singular locus is the set We are interested in the algebraic
conditions for singular solutions to happen.
First we deal with the analytic case: the graph of a singular solution
is embedded in S. We recall that such a solution may occur only
when the differential ideal generated by is not reducible. The existence of
singular solutions is not generic and we show a relationship with the
theory of differential-algebraic equations by Rabier and Rheinboldt
[9]. This is also the adaptation to holomorphic differential equations
of a result from Fukuda and Fukuda [2].
On the other hand, the Ritt-Raudenbusch theorems, related to the
decomposition of differential ideals, give the algebraic conditions to
get singular solutions for polynomial differential systems. This also
indicates the non genericity of singular solutions existence.
