A considerable amount of work in topos theory has been published in Iran in the past decade. Of particular interest to me are papers by Khanjanzadeh and Madanshekaf. Has anyone here been in contact with these authors and/or is anyone able to access the website of Semnan University where they work to get their contact details?
Madanshekaf's email is available on their ArXiv postings: amadanshekaf@semnan.ac.ir
Thanks Kevin! I also found an email address for Khanjanzadeh Seresti in a more recent preprint.
