Minimal ($\tau$-)tilting infinite algebras

Motivated by a new conjecture on the behavior of bricks, we start a systematic study of minimal $\tau$-tilting infinite algebras. In particular, we treat minimal $\tau$-tilting infinite algebras as a modern counterpart of minimal representation infinite algebras and show some of the fundamental similarities and differences between these families. We then relate our studies to the classical tilting theory and observe that this modern approach can provide fresh impetus to the study of some old problems. Finally, we show that in order to verify the conjecture it is sufficient to treat those minimal $\tau$-tilting infinite algebras where almost all bricks are faithful.
