An application of computer algebra to algebraic topology

open access: yesInternational Journal of Computer Mathematics, 1990
In this work we study a certain formal power series that is of considerable interest to algebraic topologists, the [p k ]-series. We define the series in a purely combinatorial way and indicate its usefulness. Then, by using computer algebra techniques, we compute it up to a high coefficient.

Topological Methods for Studying Contextuality: N-Cycle Scenarios and Beyond

open access: yesEntropy, 2023
Simplicial distributions are combinatorial models describing distributions on spaces of measurements and outcomes that generalize nonsignaling distributions on contextuality scenarios.

The Viro Method for Construction of Piecewise Algebraic Hypersurfaces

open access: yesAbstract and Applied Analysis, 2013
We propose a new method to construct a real piecewise algebraic hypersurface of a given degree with a prescribed smoothness and topology. The method is based on the smooth blending theory and the Viro method for construction of Bernstein-Bézier algebraic

Dynamics of Ion Channels via Non-Hermitian Quantum Mechanics

open access: yesEntropy, 2021
We study dynamics and thermodynamics of ion transport in narrow, water-filled channels, considered as effective 1D Coulomb systems. The long range nature of the inter-ion interactions comes about due to the dielectric constants mismatch between the water
