Nonintegrability of a system of interacting particles with the Dyson potential. (English. Russian original) Zbl 0972.70016
Dokl. Math. 59, No. 3, 485-486 (1999); translation from Dokl. Akad. Nauk, Ross. Akad. Nauk 366, No. 1, 30-31 (1999).
This paper deals with the integrability of the dynamic system of \(n\) interacting particles with the Dyson potential \(V(z)= \ln|\sin z|\). The authors analyze the problem by using previous results by V. V. Kozlov. In the complex variables setting, they find that the system has only one single-valued polynomial first integral.
