摘要
We first review the properties of the conventional -functions of the KP and Toda-lattice hierarchies. A straightforward generalization is then discussed. It corresponds to passing from differential to finite-difference equations; it does not involve however the concept of operator-valued -function nor the one associated with non-Cartanian (level ) algebras. The present study could be useful to understand better -free fields and their relation to ordinary free fields.
