proach, i.e. complexifying the ODE, is generally faster, but riskier if you are not used to complex numbers. This is the case whether you use the second ...

Introduction. We want to describe a procedure, called complexification, that enlarges real vector spaces to complex vector spaces in a natural way.

For instance, we prove that if the complexification has only generic singularities then a polynomial differential equation (1) as above, which is integrable in ...
