论文摘要
Bongartz（2013） and Ringel（2011） proved that there is no gaps in the sequence of lengths of indecomposable modules for the ?nite-dimensional algebras over algebraically closed ?elds. The present paper mainly studies this "no gaps" theorem as to cohomological length for the bounded derived category Db（A） of a gentle algebra A: if there is an indecomposable object in Db（A） of cohomological length l > 1, then there exists an indecomposable with cohomological length l-1.
