Nonvanishing minors of eigenvector matrices and consequences

Special Matrices
For a matrix M∈Kn×n{\bf{M}}\in {{\mathbb{K}}}^{n\times n}, we establish a condition on the Galois group of the characteristic polynomial φM{\varphi }_{{\bf{M}}} that induces nonvanishing of the minors of the eigenvector matrix of M{\bf{M}}.

Mereological approach to higher-order structure in complex systems: From macro to micro with Möbius

Physical Review Research
Relating macroscopic observables to microscopic interactions is a central challenge in the study of complex systems. While current approaches often focus on pairwise interactions, a complete understanding requires going beyond these to capture the full ...

Galois Connections and Fixed Point Calculus [PDF]

, 2002
Fixed point calculus is about the solution of recursive equations defined by a monotonic endofunction on a partially ordered set. This tutorial presents the basic theory of fixed point calculus together with a number of applications of direct relevance to the construction of computer programs.

Monodromy of a Class of Logarithmic Connections on an Elliptic Curve

Symmetry, Integrability and Geometry: Methods and Applications, 2007
The logarithmic connections studied in the paper are direct images of regular connections on line bundles over genus-2 double covers of the elliptic curve.
