At last we give an estimate of the maximum number of isolated limit integral surfaces passing through certain type of higher order singular points.doi:10.1007/BF02006739Yuanxun QinHuaizhong ZhaoSpringer-Verlag应用数学学报(英文版)Y.S. Chin, H.Z. Zhao, Theory of the Singular Points of Ordinary ...
We generalize the notions of ordinary points and singularities from linear ordinary differential equations to D-finite systems. Ordinary points and apparent singularities of a D-finite system are characterized in terms of its formal power series solutions. We also show that apparent singularities can ...

However, fractional extensions of ordinary models have been showing improvements in fitting real and experimental data [28]. This improvement, in general, is attributed to the memory and long-range correlation effects presented in the fractional formulation [29]. The fractional diffusion equation is ...

We study second-order ordinary differential equations of Newtonian type. The forcing terms under consideration are the product of a nonlinearity which is singular at the origin with an indefinite weight. Under some additional assumptions...

The method is enabled by the one-dimensional state-space, which leads to the study of ordinary differential equations (ODEs), rather than PDEs, and it does not extend to higher dimensional settings. Similar methods based on guess-and-verify approach have also been used by Ekström et al. ...
This paper deals with singularly perturbed systems of ordinary differential equations posed as boundary value problems on an infinite interval. The system is assumed to consist of singularly perturbed equations and unperturbed equations and to have a singularity of the second kind at $\infty $. Under...
