... Taking into account that e γ ∈ ℜ , the last condition implies that S is pure imaginary, i.e., S = is, s ∈ ℜ . Thus, equation(8) has bounded solutions ∀ s ∈ ℜ . Notice that for a purely imaginary shift parameter, the ... Lihat dokumen lengkap

... Thus, starting from the free action of the (4, 4, 0) multiplet and gauging a symmetry of this action, we have eventually arrived at the free action of the multiplet (3, 4, 1)! As distinct from the previous example, in ... Lihat dokumen lengkap

... In the spirit of the PT -symmetric quantum mechanics (PTS QM, introduced and made popular mainly in [5, 6, 7, 8, 9, 10]) we returned to the Jevicki’s and Rodrigues’ problem. In a comment [11] on [4] we recommended ... Lihat dokumen lengkap

... Abstract. The orthogonality relations of multivariate Krawtchouk polynomials are dis- cussed. In case of two variables, the necessary and sufficient conditions of orthogonality is given by Gr¨ unbaum and Rahman in [SIGMA ... Lihat dokumen lengkap

... In the same direction, the growth of research in theoretical physics and quantum optics has revealed the importance of the coherent states and hence the entanglement of the bosonic, su(2) and su(1,1) coherent states has ... Lihat dokumen lengkap

... There exist different versions of the WDVV equation in the literature, so let us be more specific. Originally, the WDVV equation appeared as a consistency relation in topological field theory, where the puncture operator ... Lihat dokumen lengkap

... Let us mention also that operators of Dunkl-type have also been used in [10] and [5] to construct some polynomial eigenvalue solutions. In these cases however, the Dunkl operators are not symmetrizable, and the ... Lihat dokumen lengkap

... The next proposition is a generalization of Proposition 3.1 of [10], in which we give a necessary and sufficient condition for uniqueness of the one-codimensional abelian normal subgroup. Proposition 8. Let G be a ... Lihat dokumen lengkap
