[HTML][HTML] Exact categories
T Bühler - Expositiones Mathematicae, 2010 - Elsevier
We survey the basics of homological algebra in exact categories in the sense of Quillen. All
diagram lemmas are proved directly from the axioms, notably the five lemma, the 3× 3 …

Cluster categories for algebras of global dimension 2 and quivers with potential
C Amiot - Annales de l'institut Fourier, 2009 - numdam.org
The cluster category associated with a finite-dimensional hereditary algebra was introduced
in [21](and in [26] for the An case). It serves in the representation-theoretic approach to …

Integral transforms and Drinfeld centers in derived algebraic geometry
We study the interaction between geometric operations on stacks and algebraic operations
on their categories of sheaves. We work in the general setting of derived algebraic …

M Kontsevich, Y Soibelman - Homological Mirror Symmetry: New …, 2008 - Springer
We develop a geometric approach to A-infinity algebras and A-infinity categories based on
the notion of formal scheme in the category of graded vector spaces. The geometric …

We define and investigate deformed n-Calabi–Yau completions of homologically smooth
differential graded (= dg) categories. Important examples are: deformed preprojective …

Derived equivalences from mutations of quivers with potential
B Keller, D Yang - Advances in Mathematics, 2011 - Elsevier
We show that Derksen–Weyman–Zelevinsky's mutations of quivers with potential yield
equivalences of suitable 3-Calabi–Yau triangulated categories. Our approach is related to …
