comment Incremental averageing
Can you elaborate on why precision errors are smaller in the second expression? Does the first expression contain a subtraction of nearly equal values?

comment Obtaining a bound on the differential operator
This almost makes sense. But the left hand side of the inequality uses $\frac{du}{dy}$, not $\left| \frac{du}{dy}\right|$. Unless it is somehow implicitly assumed that $\frac{du}{dy}>0$, I just can't see how we can conclude this.

comment Explaining the physical meaning of an eigenvalue in a real world problem
The question is about understanding and interpreting the eigenvalues/eigenvectors, not finding a method to solve the equation.

comment Factorizing a saddle point operator
@ShuhaoCao: It is the divergence operator, but my current formulation is continuous, not discrete. For simplicity, I'm currently considering a 1D case where the divergence and gradient operators are equivalent. In the future, I'd like to consider higher dimensional cases where $u_1$ is, in fact, vector valued.

comment Factorizing a saddle point operator
@RobertLewis: LU is not favorable because the resulting discrete linear operator is large. I'm trying to avoid a large solve by splitting the continuous operator before discretizing the system.
