Recurrences in processes with long-term memory
Eduardo G. Altmann
Since the work of Poincare on the stability of the solar system, recurrence is a fundamental concept in mathematics and physics. More recently, the time between recurrences of events of the same type has been successfully applied in the characterization of dynamical systems and time series in fields ranging from finance to earthquakes. In this seminar, I will investigate the statistics of recurrences in systems with long-term memory, drawing some formal analogies between physical systems and linguistic systems. First, I show that there is no unique correspondence between the recurrence time distribution and the auto-correlation function, shedding new light on the interpretation of previous results in the literature. Finally, I will report on an ongoing investigation of the recurrence between words in written text. It suggests that different classes of words in the same frequency range can have statistically distinct recurrence patterns. I will conclude with some speculative connections to psycholinguistic mechanisms for word choice.
