More Special Functions Trapped
We extend the technique of using the Trapezoidal Rule for efficient
evaluation of the Special Functions of Mathematical Physics given by integral
representations. This technique was recently used for Bessel functions, and
here we treat Incomplete Gamma functions and the general Confluent
Hypergeometric Function.Comment: 6 page
Landen inequalities for special functions
In this paper our aim is to present some Landen inequalities for Gaussian
hypergeometric functions, confluent hypergeometric functions, generalized
Bessel functions and for general power series. Our main results complement and
generalize some known results in the literature.Comment: 7 pages, to be published in Proc. Amer. Math. So
Special Functions in Minimal Representations
Minimal representations of a real reductive group G are the `smallest'
irreducible unitary representations of G. We discuss special functions that
arise in the analysis of L^2-model of minimal representations.Comment: To appear in Contemporary Mathematics, Amer. Math. Soc;

Special functions from quantum canonical transformations
Quantum canonical transformations are used to derive the integral
representations and Kummer solutions of the confluent hypergeometric and
hypergeometric equations. Integral representations of the solutions of the
non-periodic three body Toda equation are also found. The derivation of these
representations motivate the form of a two-dimensional generalized
hypergeometric equation which contains the non-periodic Toda equation as a
special case and whose solutions may be obtained by quantum canonical
transformation.Comment: LaTeX, 24 pp., Imperial-TP-93-94-5 (revision: two sections added on
the three-body Toda problem and a two-dimensional generalization of the
hypergeometric equation
