Variational approach to a class of nonlinear oscillators with several limit cycles [PDF]
, 2001 We study limit cycles of nonlinear oscillators described by the equation $\ddot x + \nu F(\dot x) + x =0$. Depending on the nonlinearity this equation may exhibit different number of limit cycles.

On the bivariate spectral quasi-linearization method for solving the two-dimensional Bratu problem
Open Physics, 2018 In this paper, a bivariate spectral quasi-linearization method is used to solve the highly non-linear two dimensional Bratu problem. The two dimensional Bratu problem is also solved using the Chebyshev spectral collocation method which uses Kronecker ...

Riccati-parameter solutions of nonlinear second-order ODEs
, 2008 It has been proven by Rosu and Cornejo-Perez in 2005 that for some nonlinear second-order ODEs it is a very simple task to find one particular solution once the nonlinear equation is factorized with the use of two first-order differential operators. Here,
