I have been a Higher Structures Research Group member at FGC for several years. The Center organizes periodic local and international activities.
FGC's webpage: see the link
For online seminars, see the group's seminar page or researchseminars.org. To subscribe to the mailing list, contact Kazım İlhan İkeda (FGC-Boğaziçi Univ.).
Here is the Center's YouTube channel, where you can find a playlist of the recordings.
This is an online program that pairs undergraduate students studying mathematics at universities in Türkiye with graduate students and young researchers at institutions worldwide to work together on selected math books or articles. I served as a mentor between 2021 and 2023. It was a fun and fruitful experience. I wish I had such an opportunity during my undergrad years. Currently, I am enjoying my retirement.
For the program's homepage, see the link here.
