Supersymmetry transformations for singular potentials
Supersymmetry transformations singular potentials
2011/3/2
Wemake a detailed study of the first and second-order SUSYpartners of a one-dimensional free Hamiltonian with a singular perturbation proportional to a Dirac delta function. It is shown that the secon...
On the canonical structure of regular pencil of singular matrix-functions
singular matrix-functions math
2010/11/15
The work is devoted to investigation of the canonical structure of regular, in domain of definition ${\cal U}\subseteq {\mathbb R}^{m}$, the pencil of matrix-functions $A(x)+\lambda B(x)$. It is supp...
