Analytic nilpotent centers with analytic first integral

Nonlinear Analysis: Theory, Methods & Applications, 2010
This paper considers an analytic system having an isolated nilpotent singularity at the origin: \[ \dot{x}=y+X_2(x,y), \dot{y}=Y_2(x,y). \] A necessary condition for local analytic integrability is given. The condition can be verified using the normal form theory.

Analytical centers of the East

Вісник Книжкової палати, 2021
У статті здійснено огляд стратегічних інститутів і "мозкових центрів" окремих країн Сходу у розрізі їхніх національних аналітичних традицій та розгалуженої багатоярусної самосвідомості. Схід вирізняється різноманіттям релігійно-філософських аналітичних традицій, відповідно, в азійських країнах діяльність аналітичних центрів має різні форми.

ANALYTIC CENTER OF NILPOTENT CRITICAL POINTS

International Journal of Bifurcation and Chaos, 2012
For third-order nilpotent critical points of a planar dynamical system, the analytic center problem is completely solved in this article by using the integrating factor method. The associated quasi-Lyapunov constants are defined and their computation method is given.
