A simple proof of the Jamiolkowski criterion for complete positivity of linear maps
D. Salgado, J. L. Sanchez-Gomez, M. Ferrero
We give a simple direct proof of the Jamiolkowski criterion to check whether a linear map between matrix algebras is completely positive or not. This proof is more accesible for ph…

Integrable systems on the lattice and orthogonal polynomials of discrete variable
M. Lorente
Some particular examples of classical and quantum systems on the lattice are solved with the help of orthogonal polynomials and its connection to continuous models are explored.
