Should I mention my university name when publishing a paper if I'm tenured teacher but not researcher? I'm teacher in a French university (I don't know if the right english term is 'tenured', I mean I'm hired permanently in this university, not temporarily), but I don't have any research role and I'm not connected to any research lab.

Still, I continue to do research during my free time (mostly continuing what I did during my PhD, not connected to the local labs research fields), and I would like to submit a paper to a journal.

Question: as I'm not hired by my university to do research, but only teaching, can I submit a paper like this:


  On the cohomology of finite infinite categories
  John Doe  
  
  University of Cityname
  283, rue de Paris - 12345 CITY
  john.doe@univ-city.fr


or should I submit it this way, without any university name:


  On the cohomology of finite infinite categories
  John Doe
  john.doe@gmail.com


What could be the potential problems if I use my university name / edu-email address, whereas I'm not hired as researcher?
The fact that this research isn't part of your job shouldn't prevent you from giving your employer as your affiliation. A paper by David Pincus about certain weak forms of the axiom of choice in set theory (J. Symbolic Logic 67 (1997) 438-456) lists his affiliations as "Department of Anesthesia, Harvard Medical School, Massachusetts General Hospital, Cambridge City Hospital". I can assure you that none of these anesthesiology departments paid David to prove theorems in set theory; he did this work in his free time.
