Laplace approximation for Bessel functions of matrix argument
The authors present Laplace approximations to Bessel functions of matrix argument and to the confluent type II matrix argument hypergeometric function. A collection of results concerning the theoretical properties of the various Laplace approximations is proved. In particular, it is shown that suitably calibrated versions of the approximations inherit the symmetries and confluence relations satisfied by the original functions. A series of tables with results of calculations is given.
