Apparently (for I am no mathematician nor a historian of mathematics) there were two famous British mathematicians, G. F. Hardy and J. E. Littlewood, who famously collaborated on a lot of stuff that would have even Marc crying “Reader’s Digest!” Before they began their collaboration, which they did almost exclusively through written correspondence, they decided to formulate some rules which would protect their “personal freedom,” whatever that means.
I think they bear consideration as we begin our own collaboration in considerably closer quarters.
The first of them said that, when one wrote to the other, …, it was completely indifferent whether what they wrote was right or wrong …
The second axiom was to the effect that, when one received a letter from the other, he was under no obligation whatsoever to read it, let alone to answer it …
The third axiom was to the effect that, although it did not really matter if they both thought about the same detail, still, it was preferable that they should not do so.
And, finally, the fourth, and perhaps most important axiom, stated that it was quite indifferent if one of them had not contributed the least bit to the contents of a paper under their common name …
