I have done a research project for a vocational masters. During then, there was a major disruption in the teaching department which affected the supervision process. However, I was already having another Masters degree and was in my last stage of a PhD degree program as well. So I planned, conducted, analysed and wrote my research thesis without any supervision. The only supervision I can think of is reading the completed thesis by my supervisor (which was assigned to me in later stage of the project, who managed to give very minor comments which I feel was not significant at all as I did not have to change things except some paraphrasing and proofreading as I'm not a native English speaker.
Now I'm in the process of publishing a paper from that research and wondering if I can publish it as a single author paper? I normally do not mind to involve my supervisor or any team member who worked with me in a study as long as I believe there was some how a considerable contribution, but in this time, my work is asking me to publish a single author paper as part of the requirement for promotion so there is another reason to push me more critical for whom should be involved. So do you think it is okey based on the above situation to proceed in publishing the work by my own as a single author paper?
Thank you in advance
