We analyse the Witten-Woronowicz's type deformations of the Lie superalgebras spl(N, 1) and obtain deformations parametrized by N (N − 1)/2 independent parameters for N > 2 and by three parameters for N = 2. For some of these algebras, finite dimensional representations can be constructed in terms of finite difference operators , providing operators that are relevant for the classification of q...

We analyse the Witten-Woronowicz's type deformations of the Lie su-peralgebra osp(2,2) and obtain a deformation parametrized by three independent parameters. For some of these algebras, finite dimensional representations are formulated in terms of a finite difference operator, providing operators that are relevant for the classification of quasi exactly solvable, finite difference equations. Si...

Purpose For Chinese companies that cross-list in A share and Hong Kong (H share) markets, the H price has been consistently lower than by an average of 85% recent years. This is puzzling because most institutional differences between two markets have eliminated since 2007. The purpose this study to explain puzzle difference A+H companies. Design/methodology/approach Using all firms period 2007–...

This paper presents some new propositions related to the fractional order h-difference operators, for case of general quadratic forms and polynomial type, which allow proving stability systems, by means discrete Lyapunov direct method, using functions, functions any positive integer order, respectively. Some examples are given illustrate these results.

In this work we solve numerically a boundary value problem for second order fuzzy differential equations under generalized differentiability in the form y′′(t) = p(t)y′(t) + q(t)y(t) + F(t) y(0) = γ, y(`) = λ where t ∈ T = [0, `], p(t) ≥ 0, q(t) ≥ 0 are continuous functions on [0, `] and [γ]α = [γα ,γα ], [λ ] α = [λ α ,λ α ] are fuzzy numbers. There are four different solutions of the problem ...
