Query: A q-analogue of Graf's addition formula for the Hahn-Exton q-Bessel
  function   An addition and product formula for the Hahn-Exton $q$-Bessel function,
previously obtained by use of a quantum group theoretic interpretation, are
proved analytically. A (formal) limit transition to the Graf addition formula
and corresponding product formula for the Bessel function is given.
