Some authors have published a very long complex research paper (on ArXiv, theoretical computer science, math, category theory) and it contains references to three additional research-technical reports, the references of two of them included the note "available from authors upon request".
I have contacted the authors with kind request to receive those additional reports, but currently I have not received any answer. Three days have gone, I am patiently waiting, but I am loosing my hopes.
There is additional context to this story. I have posted some questions in the forums about this paper. Some threads have grown fairly large and contain valuable content. Some are not. I have been in loose touch with authors before and they indicated to me that they were feeling offended by my public questions. Although I have not seen anything offending in them (except for one post, but it was made by top notch scientist who was just jealous, it can be felt pretty clearly. It is not the usual course of actions, of course, but it happened this time, maybe the vibe of my post was a bit informal) and now I am afraid that they doesn't want to hear from me. Otherwise the authors have been very supportive and very open to the suggestions that can improve their article, but I have made almost none (others have made a lot as one can see from the 3rd version and from the acknowledgments).
It can be hard to decide. From the one side - I should be able to feel when "no answer" is answer too. From the other side - maybe apologize and more explanation can help?
It may be possible that the authors are on the Summer vacation.
There is some personal story as well. I have spent endless hours past year trying to read this article and all the necessary books, referenced articles. I have really postponed many assignments and duties and even incurred some loses due to this. So, it is very sad no to receive any answer. From the other side - I have managed to understand this paper and I can survive and do my research without those technical reports, I have ideas that are superior to any such report as far as I can guess about their content. But ideas are can not be comparable to the real work done and real report written, so I should be humble.
So - should I be ready to accept that no further communication is possible or is it tolerable (after some week) to try another (very small, gentle and final) communication effort?
