Suppression of Ecological Competition by Apex Predator
Taksu Cheon, Shigemi Ohta
In the framework of Lotka-Volterra dynamics with evolutionary parameter variation, it is shown that a system of two competing species which is evolutionarily unstable, if left to t…

Spectral properties on a circle with a singularity
Tamas Fulop, Izumi Tsutsui, Taksu Cheon
We investigate the spectral and symmetry properties of a quantum particle moving on a circle with a pointlike singularity (or point interaction). We find that, within the U(2) fami…

Evolutionary Stability of Ecological Hierarchy
Taksu Cheon
A self-similar hierarchical solution that is both dynamically and evolutionarily stable is found to the multi dimensional Lotka-Volterra equation with a single chain of prey-predat…
