The Emden differential equation is one of the most widely studied and challenging nonlinear dynamics equations in literature. It finds applications various areas study such as celestial mechanics, fluid Steller structure, isothermal gas spheres, thermionic currents so on. Because importance equation, method generalized Sundman transformation (GST) proposed by Nakpim Meleshko used for linearizin...

We obtain infinitely many non-radial singular solutions of LaneEmden equation ∆u + u = 0 in RN\{0}, N ≥ 4 with N + 1 N − 3 < p < pc(N − 1) by constructing infinitely many radially symmetric regular solutions of equation on SN−1 ∆SN−1w − 2 p− 1 [ N − 2− 2 p− 1 ] w + w = 0.

Systems of Lane-Emden equations arise in the modelling of several physical phenomena, such as pattern formation, population evolution and chemical reactions. In this paper we construct Noether and partial Noether operators corresponding to a Lagrangian and a partial Lagrangian for a coupled Lane-Emden system. Then the first integrals with respect to Noether and partial Noether operators are obt...
