Math. 227, 79-88 (1999). The main goal of this paper is to formulate a multi-dimensional analogue of the Krichever construction in terms of the Dirac operator. The arguments used in the proof make possible to replace the multi-dimensional Dirac operator by an arbitrary elliptic differential operator. There are used standard techniques from the theory of pseudodifferential operators. After deducing the main result under the additional assumption that the Agmon-Seeley condition is satisfied, the author shows that this hypothesis can be removed.For the entire collection see [Zbl 0904.00041].
