I am new to this and I wanted to ask, when should we invite co-authors and when should we write alone?
Can somebody invite a co-author to join an article about a project solely done by the main author? Perhaps for the purposes of gaining more experience in publishing,building professional relationships?

What are the rules?

Thank you

I am in need of some wise advice from senior PhD students. What would be acceptable while publishing?

Is co-authoring your mentor on invited papers good?
I have been told that I need to stick with my supervisor on papers and that I should prefer not to publish independently. Is that right?

What are your recommendations, advice and tips regarding publishing ?

Thanks !!
