A fractional-order SEIHDR model for COVID-19 with inter-city networked coupling effects
Zhenzhen Lu, Yongguang Yu, YangQuan Chen +4
In this paper, a mathematical model is proposed to analyze the dynamic behavior of COVID-19. Based on inter-city networked coupling effects, a fractional-order SEIHDR system with t…
Forecast analysis of the epidemics trend of COVID-19 in the United States by a generalized fractional-order SEIR model
Conghui Xu, Yongguang Yu, QuanChen Yang +1
In this paper, a generalized fractional-order SEIR model is proposed, denoted by SEIQRP model, which has a basic guiding significance for the prediction of the possible outbreak of…
Analytical calculation of the inverse nabla Laplace transform
Yiheng Wei, YangQuan Chen, Yuquan Chen +1
The inversion of nabla Laplace transform, corresponding to a causal sequence, is considered. Two classical methods, i.e., residual calculation method and partial fraction method ar…
Global Padé approximations of the generalized Mittag-Leffler function and its inverse
Caibin Zeng, YangQuan Chen
This paper proposes a global Padé approximation of the generalized Mittag-Leffler function with . This uniform approximation can account for both the…
