✦ Synopsis

The electronic, optical and elastic properties of the ternary II-VI semiconductor alloys Cd 1-x Zn x Te are calculated by the sp 3 s * semi-empirical tight-binding theory and the bondorbital model. We found a nonlinear decrease of the transverse effective charge and refractive index and a nonlinear increase of the bandgap and elastic constants with increasing Zn composition x. For all these behaviours, the corresponding bowing factors are predicted. The results are compared with previous theoretical estimates and experiments.

In this paper we investigate the global asymptotic stability of the recursive , n s 0, 1, . . . , where ␣, ␤, ␥ G 0. We show that the unique positive equilibrium point of the equation is a global attractor with a basin that depends on the conditions posed on the coefficients.

For every integer m ≥ 3 and every integer c, let r m c be the least integer, if it exists, such that for every 2-coloring of the set 1 2 r m c there exists a monochromatic solution to the equation The values of r m c were previously known for all values of m and all nonnegative values of c. In this
