Proof of unsolvability of $q$ -Bessel equation using valuations
[Full Article (PDF)] [MathSciNet Review (HTML)] [MathSciNet Review (PDF)]

Abstract:
In this paper, we prove unsolvability of the

$q$ -Bessel equation associated with one of the

$q$ -Bessel functions,

$J_\nu^{(3)}$ , using the notion of the difference field extension of valuation ring type.

Keywords: solvability, algebraic independence.
