Abstract

Let kk be a field, QQ a finite directed graph, and kQkQ its path algebra. Make kQkQ an \NN\NN-graded algebra by assigning each arrow a positive degree. Let II be a homogeneous ideal in kQkQ and write A=kQ/IA=kQ/I. Let \QGrA\QGr A denote the quotient of the category of graded right AA-modules modulo the Serre subcategory consisting of those graded modules that are the sum of their finite dimensional submodules. This paper shows there is a finite directed graph QQ' with all its arrows placed in degree 1 and a homogeneous ideal IkQI'\subset kQ' such that \QGrA\QGrkQ/I\QGr A \equiv \QGr kQ'/I'. This is an extension of a result obtained by the author and Gautam Sisodia.
