Some necessary information:
I study at European university A, but did my degree project at European university B.
I will not get a degree from B but from A.
I was supervised by a professor and one of his assistance at B.
My supervisor at A only received regular updates, but wasn't involved in any other way.
Officially the professor at A is grading my work (in reality he probably will just call and ask the professor at university B for the grade, but nonetheless).
Question:
I'm currently making the last thing for my thesis: The titlepage. How do I refer to the two professors and the assistant on the titlepage? Who is the supervisor, who the PI? I don't want to step on anybody's toes. I definitely need to mention all three of them.
Furthermore I ask myself whether it is acceptable to put the logo of both universities on the title. I feel like it is weird because I only get a degree from A, but also feel like the professor at B will be offended if I don't.
I know this is a silly question, but maybe you can help me resolve this.
