I'm a Ph.D. student in Mathematics (Dynamical Systems) at Kyoto University. I did my undegraduate in Mathematics and Masters in Applied Mathematics at the University of the Philippines-Diliman.
Under the supervision of Prof. Hiroshi Kokubu, my thesis topic is on finding a lower bound for the topological entropy of multivalued maps coming from a time series of an unknown dynamical system. Understanding time series is crucial if we want to know something about how the true but unknown underlying system that drives it behaves. The method of estimation is by means of a multivalued map obtained from a time series and showing a horseshoe-like dynamics present in this map. The notion of symbolic dynamics and phase-space reconstruction play crucial roles as well.
