Differential graded algebras over some reductive group (1704.01734v1)
Published 6 Apr 2017 in math.RA and math.CT
Abstract: We study the general properties of commutative differential graded algebras in the category of representations over a reductive algebraic group with an injective central cocharacter. Besides describing the derived category of differential graded modules over such an algebra, we also provide a criterion for the existence of a t-structure on the derived category together with a characterization of the coordinate ring of the Tannakian fundamental group of its heart.
