## Abstract We will find a positive constant Σ~2~ such that for any 2__π__ ‐periodic function __h__ (__t__) with zero mean value, the quadratic Newtonian equation __x__ ″ + __x__^2^ = __σ__ + __h__ (__t__) will have exactly two 2__π__ ‐periodic solutions with one being unstable and another being tw

We give a purely analytical perturbation method of solution of the van der Pol equation, whereby the periodic solution can be actually developed in the form of a power series in the damping parameter up to any desired order and thus analysed in detail. The coefficients of the series solution, which

We employ elliptic regularization and monotone method. We consider X⊂R n (n 1) an open bounded set that has regular boundary C and Q = X×(0,T), T>0, a cylinder of R n+1 with lateral boundary R = C×(0,T).
