Mirror-reflective algebras and Tachikawa's second conjecture

Hongxing Chen, Ming Fang, Changchang Xi

Given an algebra with an idempotent, we introduce two procedures to construct families of new algebras, termed mirror-reflective algebras and reduced mirror-reflective algebras. We…

Symmetric subcategories, tilting modules and derived recollements

Hongxing Chen, Changchang Xi

For any good tilting module over a ring , there exists an -symmetric subcategory of a module category such that the derived category of the endomorphism rin…

Derived decompositions of abelian categories I

Hongxing Chen, Changchang Xi

Derived decompositions of abelian categories are introduced in internal terms of abelian subcategories to construct semi-orthogonal decompositions (or Bousfield localizations, or h…

Rigidity dimension - a homological dimension measuring resolutions of algebras by algebras of finite global dimension

Hongxing Chen, Ming Fang, Otto Kerner +2

A new homological dimension is introduced to measure the quality of resolutions of `singular' finite dimensional algebras (of infinite global dimension) by `regular' ones (of finit…

Ortho-symmetric modules, Gorenstein algebras and derived equivalences

Hongxing Chen, Steffen Koenig

A new homological symmetry condition is exhibited that extends and unifies several recently defined and widely used concepts. Applications include general constructions of tilting…
