Contact symmetries of the Helmholtz form
In this paper, vector fields which are symmetries of the contact ideal are studied. It is shown that contact symmetries of the Helmholtz form transform a dynamical form to a dynamical form which is variati...

Logistic equation as example of simple nonlinear dynamics system
This article analyses logistic equation as one of the simplest examples of nonlinear dynamics system. This equation is analysed in a difference form and it will be shown that in this form chaos behavior can arise. But a dif...

Cartan-Lepage forms in mechanics
We present variational principles for mechanics on the basis of the Cartan 1-form. We extend the theory to the Cartan-Lepage 2-forms related with dynamical forms and equations of motion. Explicit coordinate formula...
