Motivated by studying infinitely generated tilting modules and recollements, we consider the question of when a universal localization is homological. In this talk, we shall provide two answers to this question. As a consequence of our results, we can get a large variety of new recollements of derived module categories.
This is a joint work with Hongxing Chen.
