We prove two determinantal identities that generalize the Vandermondedeterminant identity
. In the first of our identities the set {0, ..., m} indexing the rows and columns of thedeterminant is replaced by an arbitrary finite order ideal in the set ofsequences of nonnegative integers which are 0 except for a finite numberof components. In the second the index set is replaced by an arbitraryfinite order ideal in the set of all partitions. 相似文献

Let be an even integer, . The resultant of the polynomials and is known as Wendt's determinant of order . We prove that among the prime divisors of only those which divide or can be larger than , where and is the th Lucas number, except when and . Using this estimate we derive criteria for the nonsolvability of Fermat's congruence.

We prove the explicit formula for the hyperbolic scattering determinant in the case of a general subgroup F of PSL (2, R). The class of test functions involved (not necessarily odd nor continuous) is much broader than that previously known. As an application of the technique, a new representation of the Millson-Shintani zeta function is obtained. 相似文献
