Results about persymmetric matrices over F_2 and related exponential sums
Jorgen Cherly
In this paper we expose our main results about rank problems concerning persymmetric matrices over F_2 associated to some exponential sums.
Exponential sums and rank of triple persymmetric matrices over F_2
jorgen cherly
We obtain using exponential quadratic sums, explicit expressions for the number of triple persymmetric matrices over F_2 of given rank. (A matrix [a(i,j)] is persymmetric if a(i,j)…
Exponential sums and rank of double persymmetric matrices over F_2
Jorgen Cherly
We obtain, using exponential quadratic sums, explicit expressions for the number of double persymmetric matrices with entries in F_2 of given rank. (A matix [a(i,j)) is persymmetri…
Exponential sums and rank of persymmetric matrices over F_2
Jorgen Cherly
Over the finite field with two elements, we present a method for obtaining explicit expressions for the number of rank i matrices of the form A above B, where A is persymmetric (A…
