Low-Dimensional Reduction Theory for Populations of Phase Oscillators with a Gaussian Frequency Distribution
Kai Tokunaga
Low-dimensional reduction theories such as the Ott-Antonsen ansatz have played a crucial role in the study of populations of coupled oscillators. Their application, however, has la…

Exact Low-Dimensional Reduction Theory for Populations of Stuart--Landau Oscillators
Kai Tokunaga
This paper develops an exact low-dimensional reduction theory for populations of Stuart-Landau oscillators. The theory covers two cases: in one case, coupling enters only through t…

Low-Dimensional Reduction Theory for Populations of Globally Coupled Phase Oscillators with Multiharmonic Coupling: A Method Based on OPUC Theory
Kai Tokunaga
Low-dimensional reduction theories such as the Ott-Antonsen ansatz have played a crucial role in the study of populations of coupled oscillators. However, most of these theories ap…
