on the affine line "A"1 (that is, on the complex numbers C). This equation corresponds to a flat connection on the trivial algebraic line bundle over "A"1. The solutions of the equation are of the form "cez" for constants "c". Since these solutions do not have polynomial growth on some sectors around the point ∞ in the projective line P1, the equation does not have regular singularities at ∞. (This can also be seen by rewriting the equation in terms of the variable "w" := 1/"z", where it becomes
