Abstract We recall the form factors of the two-point diagonal correlation function of the Ising model on the square lattice and their associated linear differential equations which exhibit both a "Russian-doll'' nesting, and a decomposition of the linear differential operators as a direct sum of operators. The scaling limit of these differential operators breaks the direct sum structure but not the "Russian doll'' structure, the "scaled'' linear differential operators being no longer Fuchsian. We also discuss the nature of the singularities emergingfrom this approach.
