Query: Total positivity of a class of combinatorial matrices   In this paper, we consider matrices whose entries are combinatorial sequences
which can be expressed in terms of a convolution of elementary and complete
homogeneous symmetric functions. We establish the total positivity of these
matrices using the Lindstr\"om-Gessel-Viennot Lemma.
