The numerical method is used to explore the influence of various parameters on the bifurcation of the birhythmic system, and the role of fractional derivative and L\u00e9vy noise in inducing or inhibiting birhythmicity in a time-delayed birhythmic biological system is examined in this work. First, we use a numerical method to calculate the fractional derivative, which has a fast calculation speed. Then the McCulloch algorithm is employed to generate L\u00e9vy random numbers. Finally, the stationary probability density function graph of the amplitude is obtained by Monte Carlo simulation. The results show that the fractional damping and L\u00e9vy noise can effectively control the characteristics of the birhythmic oscillator, and the change of the parameters (except the skewness parameter) can cause the system bifurcation. In addition, this article further discusses the interaction of fractional derivative and time delay in a birhythmic system with L\u00e9vy noise, proving that adjusting parameters of time delay can lead to abundant bifurcations. Our research may help to further explore the bifurcation phenomenon of birhythmic biological system, and has a practical significance.<\/jats:p>","DOI":"10.1142\/s0218127421502448","type":"journal-article","created":{"date-parts":[[2021,12,21]],"date-time":"2021-12-21T03:06:46Z","timestamp":1640056006000},"source":"Crossref","is-referenced-by-count":3,"title":["Bifurcations in a Time-Delayed Birhythmic Biological System with Fractional Derivative and L\u00e9vy Noise"],"prefix":"10.1142","volume":"31","author":[{"given":"Wenting","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Applied Mathematics, Northwestern Polytechnical University, Xi\u2019an, Shaanxi 710129, P.
