Query: Tur\'an type inequalities for confluent hypergeometric functions of the
  second kind   In this paper we deduce some tight Tur\'an type inequalities for Tricomi
confluent hypergeometric functions of the second kind, which in some cases
improve the existing results in the literature. We also give alternative proofs
for some already established Tur\'an type inequalities. Moreover, by using
these Tur\'an type inequalities, we deduce some new inequalities for Tricomi
confluent hypergeometric functions of the second kind. The key tool in the
proof of the Tur\'an type inequalities is an integral representation for a
quotient of Tricomi confluent hypergeometric functions, which arises in the
study of the infinite divisibility of the Fisher-Snedecor $F$ distribution.
