For a finite group and an algebraically closed field of characteristic for any indecomposable finite dimensional -module with vertex and a subgroup of containing there is a unique indecomposable -module of vertex being a direct summand of the restriction of to . This correspondence, called Green correspondence, was generalised by Auslander-Kleiner to the situation of pairs of adjoint functors between additive categories. In the original situation of group rings Carlson-Peng-Wheeler proved that this correspondence is actually restriction of triangle functors between triangulated quotient categories of the corresponding module categories. We review this theory and show how we got a common generalisation of the approaches of Auslander-Kleiner and Carlson-Peng-Wheeler, using Verdier localisations.
