Query: A Nice Representation for a Link between Baskakov- and
  Sz\'asz-Mirakjan-Durrmeyer Operators and their Kantorovich Variants   In this paper we consider a link between Baskakov-Durrmeyer type operators
and corresponding Kantorovich type modifications of their classical variants.
We prove a useful representation for Kantorovich variants of arbitrary order
which leads to a simple proof of convexity properties for the linking
operators. This also solves an open problem. Another open problem is presented
at the end of the paper.
