Horizontal visibility graphs: exact results for random time series
Bartolo Luque, Lucas Lacasa, Fernando Ballesteros +1
The visibility algorithm has been recently introduced as a mapping between time series and complex networks. This procedure allows to apply methods of complex network theory for ch…

The Visibility Graph: a new method for estimating the Hurst exponent of fractional Brownian motion
Lucas Lacasa, Bartolo Luque, Jordi Luque +1
Fractional Brownian motion (fBm) has been used as a theoretical framework to study real time series appearing in diverse scientific fields. Because its intrinsic non-stationarity a…
