Abstract: | In this paper, we continue to study factorization of supersymmetric (SUSY) transformations in one-dimensional Quantum Mechanics
into chains of elementary Darboux transformations with nonsingular coefficients. We define a class of potentials that are
invariant under the Darboux-Crum transformations and prove a number of lemmas and theorems substantiating the formulated conjectures
on reducibility of differential operators for spectral equivalence transformations. Analysis of the general case is performed
with all the necessary proofs. Bibliography: 27 titles.
