Derivative of the regularized upper incomplete gamma function @Suvrit Sorry to have made confusion by using different variables in the definition of $Q$. Thank you for your attention, but I cannot understand your last sentense clearly. Can you explain how to use this formula to solve my question in more detail? Thank you very much! |

Derivative of the regularized upper incomplete gamma function @Suvrit Thank you for your attention! Do you mean there is a formula for $\frac{\partial Q(x,λ)}{\partial x}$ in wikipedia? I am sorry that I did not find such a formula but only the formula $\frac{\partial\Gamma(x,λ)}{\partial x}=\ln\lambda\Gamma(x,\lambda)+\lambda T(3,x,\lambda)$ instead. If you found the formula for the derivative of $Q(x,\lambda)$ w.r.t. $x$, could you please show me the url of the wikipedia? Thank you very much! |

Is it possible to obtain the vectors orthogonal to a given one by orthogonal transformations? It's helpful of your answer. However there are some points in your answer that I cannot understand clearly since I do not major in mathematics. Could you please recommend some references or papers to explain your answer in more detail, please? Thank you very much! |

Is it possible to obtain the vectors orthogonal to a given one by orthogonal transformations? I think both of your answers are very helpful. However, since I cannot accept both of your answers in the system and the answer given by Charles Rezk is in more detail, I choose to set his answer as the accepted answer. Anyway, it's very kind of you and thank you very much! |

How to solve this optimization with the orthogonal constraint? @Robert Bryant, I am sorry to trouble you all with this simple question and I have solved it. However, I have to say that this is indeed not my homework or exam problem. I will think more by myself before posting the question next time. Thank you very much! |

What is the geometry of the intersection of some cones defined by generalized inequalities? I am reading the papers you suggested and they indeed provide an interesting standpoint for this question. Thank you very much! |
