I am a theoretical physicist working in the area of quantum field theory, mostly QCD and gauge theories. I am also interested on techniques of solution of PDEs. An incomplete list of my publications can be found on arXiv. Most of these papers appeared in refereed journals.

Uniqueness of the solution of a nonlinear PDE
The question I tried to ask is how general are these solutions. Please, could you suggest a better rewording? |

Uniqueness of the solution of a nonlinear PDE
Why did you put this on hold? What is wrong with this formulation of the question? Please, check these papers arxiv.org/abs/1412.1955 arxiv.org/abs/1409.2351 arxiv.org/abs/1306.6530 arxiv.org/abs/0907.4053 Why should not this question fit your criteria for research level? |

Asymptotic Expansion of Double integral
This is exactly what I am saying. The series in $\theta$ worsens convergence at any order. But if you permit the upper integration limit in $r$ to be finite one can study the integral in $r$ increasing this limit. |

Asymptotic Expansion of Double integral
The series for $\theta\rightarrow 0$ is very easy to compute with any software. Maple yields $\frac{2\pi}{\sin r}+\frac{\pi}{2}\frac{1}{\sin^2r|\sin r|}\theta^2+O(\theta^4)$ but the corresponding integrals in $r$ become more and more intractable due the infinite poles arising at the denominator of increasing order. Maybe, it would be more interesting to understand the behavior of the integral in $r$ taking the upper integration limit to a variable and studying what happens when this limit increases. |

Some explanation about Dynin's formalism
As soon as your discussion with Dynin is completed, I will accept this as the answer to my question. Thank you again a lot for your time and sorry for having considered you a theoretical physicist rather than a mathematician as you are. |

Some explanation about Dynin's formalism
So, why Terry Tao asked for a fix to a theorem of mine? Of course, I am a theoretical physicist so I appreciate a lot your being more mathematical oriented that helped a lot in this quest on Dynin's work. In some sense, your answer is some I expected and I think that Tao's intervention was motivated by arxiv.org/abs/0709.2042, my Physics Letters B paper. In this paper I work with theorems and is the most rigorous I have written about this matter. After that my interest diverted and I was mostly interested in applications to be compared with experiments. At the end, I am a physicist. |

Some explanation about Dynin's formalism
Dear Arnold, As you could notice by the citations in some of these papers, I am somewhat involved in this strange race. Also Terry Tao entered to comment on one of my papers finally agreeing on the fix he asked for in one of them. So, if you would like to make a complete list, my papers should be in. I think the last of the series is arxiv.org/abs/1309.3966 appeared in JHEP. I am currently applying my ideas doing computations in some processes of QCD as also you can see in arxiv.org/abs/1105.5274 appeared in Physical Review C. Thanks. |

@CharlesMatthews But you have left the link to Dynin's paper. Is it ok? |

Some explanation about Dynin's formalism
@ThomasRot Yes, the claim has been inserted by Dynin himself. My question is rather different and, I think, in the framework of MO. This author's claim implies the use of a kind of technique that I am not aware of, being a physicist, and I would like to know more about. |
