摘 要:
In this talk, some results on derived representation type will be introduced. A finite-dimensional algebra A is defined to be C-dichotomic if it has the dichotomy property of the representation type on complexes of projective modules. C-dichotomy implies the dichotomy property of representation type on the level ofhomotopycategory and derived category. If k admits a finite separable field extension K/k such that K is algebraically closed, the real number field for example, then A is C-dichotomic.As a consequence, the second derivedBrauer-Thrall type theorem holds for A, i.e., A is either derived discrete or strongly derived unbounded. This is a joint work with LiJie.
