Software for the Frobenius method for the solution of nonlinear differential equations
An algorithm and a program are described for constructing a polynomial solution of the 2nd order differential equation \(y''+w^ 2y+a sgn (y)y^{n/m}=f(t),\) where \(m=2,3\) and \(n=1,2,...,6\) while f(t) is a polynomial. Two other similar types of equations are considered as well.
