I. N. BERNSHTEĬN-I. M. GEL'FAND-S. I. GEL'FAND EQUIVALENCE FOR TRIANGULATED CATEGORIES GENERATED BY HELIXES

An analogue of the Bernshteĭn-Gel'fand-Gel'fand equivalence is proved for triangulated categories generated by exceptional sets with special properties. The proof uses the technique of mutations and helixes.
