A recent paper by R. Muolo, T. Carletti, J. P. Gleeson, and M. Asllani [Entropy 23, 36 (2021)] presents a mainly numerical study on the role of non-normality in the synchronization of coupled periodic oscillators, deriving apparent contradictions with the existing literature. Here, we show that their conclusions are artifactual due to a misinterpretation of the master stability function (MSF) formalism and confirm that the existing literature is correct. We also point to a broader existing… 
Synchronization Dynamics in Non-Normal Networks: The Trade-Off for Optimality
TLDR
It is demonstrated that, due to a transient growth that is induced by the structure’s non-normality, the system might lose synchronization, contrary to the spectral prediction, leading to a trade-off between non- normality and directedness that should be properly considered when designing an optimal network.
Comment on"Synchronization dynamics in non-normal networks: the trade-off for optimality"
Reference [1] has been harshly criticized in [2]. However, [1] is one of the first papers to highlight the important connection between synchronization of networks of oscillators and non-normality of

Master Stability Functions for Synchronized Coupled Systems
We show that many coupled oscillator array configurations considered in the literature can be put into a simple form so that determining the stability of the synchronous state can be done by a master
Maximum performance at minimum cost in network synchronization
TLDR
An extension of the well-known master stability framework to the case of non-diagonalizable Laplacian matrices is developed and it is shown how oriented spanning trees can be used to explicitly and systematically construct optimal networks under network topological constraints.

TLDR
It is shown that, unless some oscillator is linked to all the others, maximally synchronizable networks are necessarily nondiagonalizable and can always be obtained by imposing unidirectional information flow with normalized input strengths.

Construction,sensitivity index, and synchronization speed of optimal networks
The stability (or instability) of synchronization is important in a number of real world systems, including the power grid, the human brain and biological cells. For identical synchronization, the
Analysing degeneracies in networks spectra
TLDR
It is shown that a simple transformation of the network's adjacency matrix provides an understanding of the origins of occurrence of high multiplicities in the networks spectra and finds that the eigenvectors associated with the degenerate eigenvalues shed light on the structures contributing to the degeneracy.
Ordinary Differential Equations With Applications
TLDR
The ordinary differential equations with applications is universally compatible with any devices to read and is available in the digital library an online access to it is set as public so you can get it instantly.
Sensitive Dependence of Optimal Network Dynamics on Network Structure
TLDR
The results suggest that the network structure of a complex system operating near an optimum can potentially be fine-tuned for a significantly enhanced stability compared to what one might expect from simple extrapolation and suggest constraints on how close to the optimum the system can be in practice.
Robustness of optimal synchronization in real networks.
TLDR
Experimental results on the influence of connection topology on synchronization in fiber-optic networks of chaotic optoelectronic oscillators find that the recently predicted nonmonotonic, cusplike synchronization landscape manifests itself in the rate of convergence to the synchronous state.
