A note on special duality triads and their operator valued counterparts
arXiv:math/0411041
Abstract
We shall work with the so called duality triads following kwaśniewski. In particular in this note we propose some extensions of them - hence we choose such special class of triads that admit - all at once - a unified combinatorial interpretation in a way konvalina does. The proposed extensions contain also definition of operator valued arrays of konvalina-like coefficients - for the sake of future investigation and applications.
