Abstract

In this talk, results on derived representation type under the field extensions will be reported. A finite-dimensional k-algebra A is 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 homotopy and derived categories. If k admits a finite separable field extension which is algebraically closed, then A is C-dichotomic. As a consequence, the second derived Brauer-Thrall type theorem holds for A, i.e., A is either derived discrete or strongly derived unbounded. This is a joint work with Li Jie.
