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)–(iv) below: We call such a pair a tridiagonal pair on V. In this note we obtain two results. First, we show that each of A, A∗is determined up to affine transformation by the Viand Vi∗. Secondly, we characterize the case in which the Viand Vi∗all have dimension one. We prove both results using a certain decomposition of V called the split decomposition.
