Burgess-Type volume centric Bounds for Character Sums over

Aishik Chattopadhyay

We establish a Burgess-type bound for short multiplicative character sums over finite fields . Define box by $$ B=\left\{ \sum_{i=1}^{n} x_iω_i : N_i+1 \leq…

Character sums to prime power moduli evaluated at binary quadratic forms

Stephan Baier, Aishik Chattopadhyay

We establish estimates for short character sums to prime power moduli evaluated at binary quadratic forms. This complements estimates established by Heath-Brown for such character…

Small solutions of ternary quadratic congruences with averaging over the moduli

Stephan Baier, Aishik Chattopadhyay

In a recent paper, we proved that for any large enough odd modulus and fixed coprime to , the congruence \[ x_1^2+α_2x_2^2+α_3x_3^2\equi…

Character sums over co-dimension one sub-lattices in finite field extensions

Aishik Chattopadhyay

We obtain nontrivial bounds for multiplicative character sums over codimension-one sublattices of finite field extensions . This extends earlier results of Davenp…

Small Solutions of generic ternary quadratic congruences

Stephan Baier, Aishik Chattopadhyay

We consider small solutions of quadratic congruences of the form , where is an odd prime power. Here, is arbitrary but fi…

Small solutions of generic ternary quadratic congruences to general moduli

Stephan Baier, Aishik Chattopadhyay

We study small non-trivial solutions of quadratic congruences of the form , with being an odd natural number, in an average sense. T…
