چکیده
Abstract The method of blowing up points indeterminacy certain systems two ordinary differential equations is applied to obtain information about the singularity structure solutions corresponding non-linear equations. We first deal with so-called Painlevé example, which passes test, but have more complicated singularities. Resolving base in equivalent system we can explain singularities original equation. Smith example has a solution non-isolated singularity, an accumulation point algebraic Smith’s equation be written as ways. show that sequence blow-ups for both infinite. Another consider Painlevé-Ince When usual analysis applied, it possesses positive and negative resonances. three there infinite another one terminates, further gives Laurent expansion around movable pole. Moreover, even possible general after blow-ups.

Movable algebraic singularities of second-order ordinary differential equations
Any nonlinear equation of the form y′′ = ∑N n=0 an(z)y n has a (generally branched) solution with leading order behaviour proportional to (z − z0) about a point z0, where the coefficients an are analytic at z0 and aN (z0) 6= 0. We consider the subclass of equations for which each possible leading order term of this form corresponds to a one-parameter family of solutions represented near z0 by a...

متن کاملSingular Eigenvalue Problems for Second Order Linear Ordinary Differential Equations
We consider linear differential equations of the form (p(t)x′)′ + λq(t)x = 0 (p(t) > 0, q(t) > 0) (A) on an infinite interval [a,∞) and study the problem of finding those values of λ for which (A) has principal solutions x0(t;λ) vanishing at t = a. This problem may well be called a singular eigenvalue problem, since requiring x0(t;λ) to be a principal solution can be considered as a boundary co...
متن کاملNON-STANDARD FINITE DIFFERENCE METHOD FOR NUMERICAL SOLUTION OF SECOND ORDER LINEAR FREDHOLM INTEGRO-DIFFERENTIAL EQUATIONS
In this article we have considered a non-standard finite difference method for the solution of second order Fredholm integro differential equation type initial value problems. The non-standard finite difference method and the composite trapezoidal quadrature method is used to transform the Fredholm integro-differential equation into a system of equations. We have also developed a numerical met...
متن کاملLecture 18: Ordinary Differential Equations: Second Order
2. General Remarks Second order ODEs are much harder to solve than first order ODEs. First of all, a second order linear ODE has two linearly independent solutions and a general solution is a linear combination of these two solutions. In addition, many popular second order ODEs have singular points. Except for a few cases, the solutions have no simple mathematical expression. However, there is ...
