Deformation theory of Cohen-Macaulay approximation
Ile, Runar (Journal article; Peer reviewed, 2021)In [22] we established axiomatic parametrised Cohen-Macaulay approximation which in particular was applied to pairs consisting of a finite type flat family of Cohen-Macaulay rings and modules. In this sequel we study the ... -
Deformations of rational surface singularities and reflexive modules with an application to flops
Gustavsen, Trond Stølen; Ile, Runar (Journal article; Peer reviewed, 2018)Blowing up a rational surface singularity in a reflexive module gives a (any) partial resolution dominated by the minimal resolution. The main theorem shows how deformations of the pair (singularity, module) relates to ...
