• #### On the response of autonomous sweeping processes to periodic perturbations ﻿

(2016-12-01)
If $x_0$ is an equilibrium of an autonomous differential equation $\dot x=f(x)$ and $\det \|f'(x_0)\|\not=0$, then $x_0$ persists under autonomous perturbations and $x_0$ transforms into a $T$-periodic solution under ...
• #### Topological degree in the generalized gause prey-predator model ﻿

(2014-12-31)
We consider a generalized Gause prey-predator model with T-periodic continuous coefficients. In the case where the Poincar√© map P over time T is well defined, the result of the paper can be explained as follows: we locate ...
