Abstract: In [1], it was shown that the one-dimensional finite-gap Schr¨odinger operator can be extended to a second-order difference operator depending on a small parameter and commuting with some difference operator of order 2g + 1. In this case, if the small parameter tends to zero, then the second-order difference operator becomes a Schr¨odinger operator. In this paper, we construct such an extension for the finite-gap TreibichVerdier operator.
