Counting in Vieta graphs over
Bogdan Nica
We introduce and study a finite simple graph of algebraic origin: the Vieta graph on the solution set over to a symmetric, multivariate equation which is quadratic i…
On quadratic character sums over quartics
Bogdan Nica
We obtain transformation formulas for quadratic character sums with quartic and cubic polynomial arguments.
Variance of point-counts for families of cubic curves over and Jacobsthal sums
Bogdan Nica
We give explicit computations for the variance of the number of points along one-parameter families of cubic curves. We highlight evaluations of variances that involve Jacobsthal s…
Kloosterman sums over finite Frobenius rings
Bogdan Nica
We study Kloosterman sums in a generalized ring-theoretic context, that of finite commutative Frobenius rings. We prove a number of identities for twisted Kloosterman sums, loosely…
