Abstract:
In this article, we find solution representations in the compact integral
form to the Cauchy problem for a general form of the Euler-Poisson-Darboux
equation with Bessel operators via generalized translation and spherical
mean operators for all values of the parameter k, including also not
studying before exceptional odd negative values. We use a Hankel transform
method to prove results in a unified way. Under additional conditions we
prove that a distributional solution is a classical one too.
A transmutation property for connected generalized spherical mean is proved
and importance of applying transmutation methods for differential equations
with Bessel operators is emphasized. The paper also contains a short historical
introduction on differential equations with Bessel operators and a rather
detailed reference list of monographs and papers on mathematical theory and
applications of this class of differential equations.
