Title: Historical Review of Recurrence Plots,
Abstract: In the last two decades recurrence plots (RPs) were introduced in many
different scientific disciplines. It turned out how powerful this method is.
After introducing approaches of quantification of RPs and by the study of
relationships between RPs and fundamental properties of dynamical systems, this
method attracted even more attention. After 20 years of RPs it is time to
summarise this development in a historical context.
