Query: Quasi-collocation based on CCC-Schoenberg operators and collocation
  methods   We propose a collocation and quasi-collocation method for solving second
order boundary value problems $L_2 y=f$, in which the differential operator
$L_2$ can be represented in the product formulation, aiming mostly on singular
and singularly perturbed boundary value problems. Seeking an approximating
Canonical Complete Chebyshev spline $s$ by a collocation method leads to demand
that $L_2s$ interpolates the function $f$. On the other hand, in
quasi-collocation method we require that $L_2 s$ is equal to an approximation
of $f$ by the Schoenberg operator. We offer the calculation of both methods
based on the Green's function, and give their error bounds.
