Mathematical modelling of many physical processes involves rather
complex dif- ferential, integral, and integro-differential
equations which can be solved directly only in a number of cases.
Therefore, as a first step, an original problem has to be
considerably simplified in order to get a preliminary knowledge of
the most important qualitative features of the process under
investigation and to estimate the effect of various factors.
Sometimes a solution of the simplified problem can be obtained in
the analytical form convenient for further investigation. At this
stage of the mathematical modelling it is useful to apply various
special functions. Many model problems of atomic, molecular, and
nuclear physics, electrody- namics, and acoustics may be reduced to
equations of hypergeometric type, a(x)y" + r(x)y' + AY = 0 , (0.1)
where a(x) and r(x) are polynomials of at most the second and first
degree re- spectively and A is a constant [E7, AI, N18]. Some
solutions of (0.1) are functions extensively used in mathematical
physics such as classical orthogonal polyno- mials (the Jacobi,
Laguerre, and Hermite polynomials) and hypergeometric and confluent
hypergeometric functions.
