I am a PhD student at one university and an invited professor at a second, i.e. I do not have a permanent position in the second one. Now I need to indicate an affiliation in a journal paper but I do not know whether to indicate or not to indicate a university where I am an invited professor.

Which affiliation to use when publishing, when invited professor at second university
If you get support (financial and moral) from both places, you should list them both.
