On the Characteristic Polynomial of the Square Grid Graph

open access: yes, 2021
The characteristic polynomial is one of the most important invariants of a graph, with applications in everything from molecular chemistry to electrical engineering. However, despite its simple geometric structure, nobody has ever found a formula for the

Revealing the Transmission Hologram's Refractive Index Profile Stored in a Photohydrogel: A Structural Characterization

open access: yesAdvanced Optical Materials, EarlyView.
A theoretical model is developed to visualize three‐dimensional refractive index profiles in transmission holographic gratings. In this work, it is applied to photopolymerizable hydrogels, enabling detailed analysis of the internal structure of recorded holograms and their evolution under different degradation conditions.

The symplectic characteristic polynomial

open access: yes
We introduce the notion of the symplectic characteristic polynomial of an endomorphism of a symplectic vector space. This is a polynomial in two variables and can be considered as a generalization of the characteristic polynomial of the endomorphism in ...

Computing the determinant of a signed graph

open access: yesOpen Mathematics
A signed graph is a simple graph in which every edge has a positive or negative sign. In this article, we employ several algebraic techniques to compute the determinant of a signed graph in terms of the spectrum of a vertex-deleted subgraph.
