A theory for detecting the Turing instability on static and temporal multiplex networks
Joshua Ritchie
The purpose of this work is to introduce and discuss a general framework for performing a linear instability analysis on multiplex networks, in the absence of inter-layer diffusion…

Non-variational scalar field cosmology: Exact Bianchi I solutions for near-minimal scalar fields
Joshua Ritchie
The purpose of this work is to investigate spatially homogeneous and flat cosmological solutions of the Einstein equations coupled to a non-variational ``near-minimal'' scalar fiel…

A general formalism for coupling scalar fields to the Einstein equations without a variational principle
Joshua Ritchie
The purpose of this work is to discuss how matter fields are coupled to gravity within the framework of General Relativity. Our particular focus here is on the coupling of scalar f…
