Quantum Analogs of Tensor Product Representations of su(1,1)
We study representations of that can be considered as quantum
analogs of tensor products of irreducible *-representations of the Lie algebra
. We determine the decomposition of these representations into
irreducible *-representations of by diagonalizing the action of
the Casimir operator on suitable subspaces of the representation spaces. This
leads to an interpretation of the big -Jacobi polynomials and big -Jacobi
functions as quantum analogs of Clebsch-Gordan coefficients
Reve\{a,i\}ling the risks: a phenomenology of information security
In information security research, perceived security usually has a negative meaning, when it is used in contrast to actual security. From a phenomenological perspective, however, perceived security is all we have. In this paper, we develop a phenomenological account of information security, where we distinguish between revealed and reveiled security instead. Linking these notions with the concepts of confidence and trust, we are able to give a phenomenological explanation of the electronic voting controversy in the Netherlands
