Mladenov, Ivaïlo M. (ed.) et al., Proceedings of the 2nd international conference on geometry, integrability and quantization, Varna, Bulgaria, June 7–15, 2000. Sofia: Coral Press Scientific Publishing (ISBN 954-90618-2-5/pbk). 280-286 (2001).
The paper deals with a variant of the real Maxwell-Bloch equation, where a control is added to the first equation. The authors consider only feedback controls of the type \(u=-kx_2 x_3\), where \(k\) is a real constant. Thus, the aim is to characterize the dynamics of a system of ODEs dependent on a real parameter \(k\). It is shown that the system admits an infinite number of Hamilton-Poisson realizations. The stability of equilibria is analyzed as a function of the parameter \(k\). The system can be integrated via elliptic functions.
