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.

comment 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.

Please, see the answer by the author to your comments. Thanks.

comment 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.

comment 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?

comment 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.

comment Green function and translational symmetry
Did you mean "there is no way to reconstruct $\phi(t)$ ..."?

comment Green function and translational symmetry
Thanks Carlo. I think that this is the main point. but can I start from $G(t,0)$ to reconstruct in some way $G(t,t')$?

comment Solvable PDEs and their Green's functions
@CarloBeenakker: It could be having an analytical solution to compare with. Indeed, this seems the case.

comment Differentiable functions with discontinuous derivatives
My personal view is that the question OP put forward is in the wrong forum. So, unsatisfactory answers are obtained unless a mathematical-minded reader is concerned. I think that, for the sake of completeness, he should look in physics.stackexchange.com where a more appropriate audience can yield the answer he is looking for.

comment Differentiable functions with discontinuous derivatives
Of course, any Green function of the Schroedinger equation does. E.g., for a free particle you will get $t^{-\frac{1}{2}}e^{i\frac{x^2}{2t}}$ but there is plenty of cases. So, starting from Green functions like these you just have a choice to do in perturbation theory. I was also considering a two-level system but with a different parameter rather than time. Dependence on coupling in quantum field theory or just quantum mechanics in perturbation theory generally have the property you are looking for.

comment Differentiable functions with discontinuous derivatives
Indeed, there are a lot of examples coming from perturbation theory applied in physics. So, I have to agree with the comment by Alexandre Eremenko.
