I'm working on complex dynamical systems, more specifically on the local/global aspect of singular holomorphic foliations in the complex plane

Codimension of the range of certain linear operators
Ok, I asked because your last sentence was unclear to me regarding the question. Thanks for the clarification. Yet, the example I gave shows that in the formal case the question has a positive answer, and the "matrices" for formal power series are not that different from that for polynomials... In fact they are the same, the difference being on the finite support on the series given as arguments, which is not something easily read in the "matrices" (if I'm not mistaken). |

So, you mean the answer should be positive (according to your experiment), not negative, right? |

No, you're right. I was too quick. I'll modify the answer. |

Algorithm to compute a common denominator of a finite set of rational numbers
How «efficient» should it be? What is the complexity you have at your disposal right now? |

Variation of the argument of a rational function along a circle
@AliTaghavi I'm not so sure it is such a great question actually. I was aware that if $C$ is spiralling enough then you can get large variations (that's why the question is asked for circles). But you're surely right that there should exists a bound in terms of the length (or more likely «curvature deviation») of $C$. |

Matrix $A$ such that for all matrices $B$ the product $AB$ has a row with not a single zero
Your class is empty, as $B:=0$ shows. So you want to prevent such things to happen :) |
