Becker We obtain several new closed-form expressions for the evaluation of a family of infinite-domain integrals of the Whittaker functions W(x) and M(x) and the modified Bessel functions I(x) and K(x) with respect to the index [mu]. The new family of definite integrals is useful in a variety of contexts i ... [J. Math. Phys. 50, 123515 (2009)] published Mon Dec 14, 2009.

Demskoi and Jyh-Hao Lee We study limiting cases of the two known integrable chiral-type models with three-dimensional configuration space. One of the initial models is the non-Abelian Toda A model and the other was found by means of the symmetry approach by Meshkov and Demskoi [Theor. Math. Phys. 134, 351 (2003)]. The C-in ... [J. Math.

Howard Lee In the logistic map, the simplest of stable odd-numbered cycles is a 3-cycle. It comes into existence after the stable 2 cycles cease to exist. The 3-cycle is thus important as a route to chaos. In 1977 Guckenheimer et al. [J. Math. Biol. 4, 101 (1977)] first estimated the value of the control param ... [J. Math.

Yokomizo and J. C. A. Barata The existence of a classical limit describing the interacting particles in a second-quantized theory of identical particles with bosonic symmetry is proved. This limit exists in addition to the previously established classical limit with a classical field behavior, showing that the limit [h-bar]-->0 ... [J. Math.
