Following the result of Feingold and Varga, a well-known theorem of Taussky on the eigenvalue distribution is extended to block diagonally dominant matrices and block H − matrices
Shortly after this discovery concerning the KdV equation, it was shown by Magri [ 17 ] that the property of having two Hamiltonian representations was not a specific feature of the
Analytic asymptotic solutions are constructed in semiclassical approximation in a small parameter ~ , ~ → 0, in the class of functions concentrated in the neighborhood of an
In this paper, using a particular example of soliton potentials, we show that the method of SUSY QM is very helpful for finding exact propagators for Hamiltonians related by SUSY
In this light, the aim of the present paper looks natural — to construct an algebraic relation corresponding to a move 3 → 3 on a triangulation of a 4-manifold, and based on

We start by using the Lie group method of infinitesimal transformations to find all the similarity reductions of the partial differential equation to ordinary differential
Two of the exact solutions arise in the context of the Quantum Inverse Scattering Method, while the third solution uses a differential operator realisation of the su(2) Lie
