Ryser, Glynn, and the discrete Fourier transform: orthogonal schemes for the permanent

José A. R. Fonollosa

The permanent of an $n \times n$ matrix is the coefficient of the fully mixed monomial $x_{0} \dots x_{n - 1}$ in the product of its row forms $\prod_{i} (\sum_{j} b_{ij} x_{j})$ ,…

Minimum modulus for the unique multiset-sum problem

José A. R. Fonollosa

Fix n >= 2. A set A = {a_0 < a_1 < ... < a_{n-1}} of n residues in Z_N is "valid mod N" if the all-ones multiset is the only size-n multiset drawn from A whose sum is p := sum_i a_…
