We collect several basic properties of algebraic cycle complexes defined by Bloch, Friedlander, Suslin and Voevodsky, like moving lemmas, localization, homotopy invariance and Mayer-Vietoris exact sequences. We also explain a generalization of the theorem of Nesterenko/Suslin/Totaro from fields to smooth, semilocal algebras of geometric type over an ...

Abusing the Tutte Matrix: An Algebraic Instance Compression for the K-set-cycle Problem
Symposium on Theoretical Aspects of Computer Science, 2013We give an algebraic, determinant-based algorithm for the K-Cycle problem, i.e., the problem of finding a cycle through a set of specified elements. Our approach gives a simple FPT algorithm for the problem, matching the O^*(2^|K|) running time of the ...

Optimal v-cycle algebraic multilevel preconditioning
Numerical Linear Algebra with Applications, 1998We consider algebraic multilevel preconditioning methods based on the recursive use of a 2 × 2 block incomplete factorization procedure in which the Schur complement is approximated by a coarse grid matrix.

Employing the algebraic structure of the left brace and the dynamical extensions of cycle sets, we investigate a class of indecomposable involutive set-theoretic solutions of the Yang–Baxter equation having specific imprimitivity blocks.

Algebraic relaxation of an order parameter in randomly coupled limit-cycle oscillators
Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 2000In their recent paper [Phys. Rev. E 58, 1789 (1998)], Stiller and Radons (SR) study, following our earlier work [Phys. Rev. Lett. 68, 1073 (1992)], the behavior of globally and randomly coupled phase oscillators with distributed intrinsic frequencies ...
