A tau-tilting subcategory of an abelian category is an additive contravariantly finite full subcategory satisfying certain conditions. In this talk, we study tau-tilting subcategories of an abelian category with enough projective objects from several different points of view. The talk is based on joint work with S. Sadeghi and H. Treffinger; arXiv:2207.00457 [math.RT].

The talk will also be streamed on zoom, contact the seminar organiser for details.
