A major part of my research in the past few years has been aimed at giving a better understanding of the behavior of bricks over algebras. Bricks, also known as Schur representations, appear in various domains, including in stability conditions, wall-and-chamber structures, τ-tilting theory, lattice theory of torsion classes, wide subcategories, to mention just a few. Following my earlier work in my PhD studies, in a series of joint work with Charles Paquette, we treat bricks from the algebraic, combinatorial and geometric viewpoints. Our work is primarily centred around an open conjecture which we call the Second brick-Brauer-Thrall conjecture (2nd bBT). First posed in my preprint in 2019, the 2nd bBT conjecture is analogous to the celebrated Second Brauer-Thrall conjecture (now theorem) and establishes novel conceptual connections between some classical and modern aspects of representation theory, such as τ-tilting theory, geometry of the representation varieties, families of stable modules, and also behaviour of infinite dimensional modules, particularly in connection with the notion of generic modules. For further details, please see my recent work here.
