The sign of a great bibliography: I’m currently referencing two papers with the titles “Generalised domination and independence in graphs” and “Generalized independence and domination in graphs”. These two papers seem to share a starting point and a couple of results, but how they go from the one to the other is very, very different. In a way, the paper I’m working on is yet another approach to the same material, but it would be difficult to come up with yet another sensible re-ordering of those words for the title.
(And yes, the s/z difference is present in the original sources: one’s by a pair of South Africans using the Commonwealth spelling, the other’s a pair of Poles using American spelling. So I suppose that gives me two technically distinct titles I could choose, if I wanted to further obfuscate the literature.)
