Let K denote a field, and let V denote a vector space over K with finite positive dimension. We consider a pair of linear transformations A:V→V and A∗:V→V that satisfy (i) and (ii) below: We call such a pair a Leonard pair on V. It is known that there exists a basis for V with respect to which the matrix representing A is lower bidiagonal and the matrix representing A∗is upper bidiagonal. In this paper we give some formulae involving the matrix units associated with this basis.
