We consider a Bessel-type differential expression on [0, a], a > 1, with the singularity at the inner point x = 1, see (1.2) below. This singularity is in the limit point case from both sides. Therefore in a Hilbert space treatment in L2(0, a), e.g. for Dirichlet boundary conditions at x = 0 and x = a, a unique self-adjoint operator is associated with this differential expression. However, in...
