摘要：In this talk, we will introduce  some numerical invariants including cohomological length,  cohomological width, and cohomological range of a complex. The cohomological range leads to the concepts of derived bounded algebra and strongly derived unbounded algebra. Then we will describe the Brauer-Thrall type theorems for the bounded derived category of a finite-dimensional algebra. Moreover, we characterize the strongly derived unbounded algebra $A$ via the category $C_m(/proj A)$ and also the repetitive algebra $/hat{A}$, which provides a proof of the dichotomy on the representation type of $C_m(/proj A)$ and $/hat{A}$.
