Relation of stability and bifurcation properties between continuous and ultradiscrete dynamical systems via discretization with positivity: one dimensional cases
Shousuke Ohmori, Yoshihiro Yamazaki
Stability and bifurcation properties of one-dimensional discrete dynamical systems with positivity, which are derived from continuous ones by tropical discretization, are studied.…
Validation of a motion model for soccer players' sprint by means of tracking data
Takuma Narizuka, Kenta Takizawa, Yoshihiro Yamazaki
In soccer game analysis, the widespread availability of play-by-play and tracking data has made it possible to test mathematical models that have been discussed mainly theoreticall…
Poincare Map Method for Limit Cycles in a Max-Plus Dynamical System
Shousuke Ohmori, Yoshihiro Yamazaki
Dynamical properties of limit cycles in a two-dimensional max-plus dynamical system are discussed. We apply a Poincare map method to the limit cycles in order to reveal their stabi…
Analysis and application of multiplicative stochastic process with a sample-dependent lower bound
Ken Yamamoto, Yoshihiro Yamazaki
A multiplicative stochastic process with the lower bound lognormally distributed is investigated. For the process, the model is constructed, and its distribution function (involvin…
