Computation of Minimal Filtered Free Resolutions over $\mathbb{N}$-Filtered Solvable Polynomial Algebras
Abstract
Let be a weighted -filtered solvable polynomial algebra with filtration , where solvable polynomial algebras are in the sense of (A. Kandri-Rody and V. Weispfenning, Non-commutative Gr\"obner bases in algebras of solvable type. {\it J. Symbolic Comput.}, 9(1990), 1--26), and is constructed with respect to a positive-degree function on . By introducing minimal F-bases and minimal standard bases respectively for left -modules and their submodules with respect to good filtrations, minimal filtered free resolutions for finitely generated -modules are introduced. It is shown that any two minimal F-bases, respectively any two minimal standard bases have the same number of elements and the same number of elements of the same filtered degree; that minimal filtered free resolutions are unique up to strict filtered isomorphism of chain complexes in the category of filtered -modules; and that minimal finite filtered free resolutions can be algorithmically computed by employing Gr\"obner basis theory for modules over with respect to any graded left monomial ordering on free left -modules.
