Calculating Constant C in Abel's Formula for Wronskian

Click For Summary
SUMMARY

The calculation of the constant C in Abel's formula for the Wronskian of a second-order ordinary differential equation (ODE) is determined by the expression W(R) = Ce^{-\int p_1(R)dR}. If the lower limit of the integral of p_1 is zero, then C can be directly taken as W(0). Understanding the asymptotic behavior of the first-order derivatives at the origin is crucial for accurately determining C. This method provides a straightforward approach to calculating the Wronskian when the homogeneous solutions are unknown.

When dealing with Abel's formula for the wronskian of a second order ODE:

W(R)=Ce^{-\int p_1(R)dR}

and assuming that you don't know the homogeneous solutions but you know their asymptotic behavior at infinity and at the origin, how is the constant C calculated?

Thanks.

Do you know the behavior of the 1st-order derivatives at the origin? You can take C = W(0) it the integral of p_1 has 0 for lower limit. Or, is the problem more involved than that?
