Kleinian singularities, derived categories and Hall algebras
M. Kapranov, E. Vasserot
We describe the derived category of coherent sheaves on the minimal resolution of the Kleinian singularity associated to a finite subgroup G of SL(2). Then, we give an application…

Noncommutative geometry based on commutator expansions
Mikhail Kapranov
We develop an approach to noncommutative algebraic geometry ``in the perturbative regime" around ordinary commutative geometry. Let R be a noncommutative algebra and A=R/[R,R] its…
