On the spectral properties of Feigenbaum graphs
Ryan Flanagan, Lucas Lacasa, Vincenzo Nicosia
A Horizontal Visibility Graph (HVG) is a simple graph extracted from an ordered sequence of real values, and this mapping has been used to provide a combinatorial encryption of tim…
Effect of antipsychotics on community structure in functional brain networks
Ryan Flanagan, Lucas Lacasa, Emma K. Towlson +2
Schizophrenia, a mental disorder that is characterized by abnormal social behavior and failure to distinguish one's own thoughts and ideas from reality, has been associated with st…
A combinatorial framework to quantify peak/pit asymmetries in complex dynamics
Uri Hasson, Jacopo Iacovacci, Ben Davis +4
We explore a combinatorial framework which efficiently quantifies the asymmetries between minima and maxima in local fluctuations of time series. We firstly showcase its performanc…
Irreversibility of financial time series: a graph-theoretical approach
Lucas Lacasa, Ryan Flanagan
The relation between time series irreversibility and entropy production has been recently investigated in thermodynamic systems operating away from equilibrium. In this work we exp…
Time reversibility from visibility graphs of non-stationary processes
Lucas Lacasa, Ryan Flanagan
Visibility algorithms are a family of methods to map time series into networks, with the aim of describing the structure of time series and their underlying dynamical properties in…
