%0 Journal Article %T Embedding structures associated with Riordan arrays and moment matrices %A Paul Barry %J Mathematics %D 2013 %I arXiv %X Every ordinary Riordan array contains two naturally embedded Riordan arrays. We explore this phenomenon, and we compare it to the situation for certain moment matrices of families of orthogonal polynomials. %U http://arxiv.org/abs/1312.0583v1
