Abstract

In a triangulated category T with a pair of triangulated subcategories X and Y, one may consider the subcategory of extensions X*. Y.We give conditions for X*. Y to be triangulated and use them to provide tools for constructing stable t-structures. In particular, we show how to construct so-called triangles of recollements, that is, triples of stable t-structures of the form (X, Y), (Y, Z), (Z, X). We easily recover some triangles of recollements known from the literature.
