Distribution of residues modulo $p$ using the Dirichlet's class number formula

Jaitra Chattopadhyay, Bidisha Roy, Subha Sarkar +1

Let $p$ be an odd prime number. In this article, we study the number of quadratic residues and non-residues modulo $p$ which are multiples of $2$ or $3$ or $4$ and lying in the int…

Quadratic non-residues and non-primitive roots satisfying a coprimality condition

Jaitra Chattopadhyay, Bidisha Roy, Subha Sarkar +1

Let $q \geq 1$ be any integer and let $ε \in [\frac{1}{11}, \frac{1}{2})$ be a given real number. In this short note, we prove that for all primes $p$ satisfying $$ p\equiv 1\pmod{q…

Restricted-sum-dominant sets

Raj Kumar Mistri, R. Thangadurai

Let $A$ be a nonempty finite subset of an additive abelian group $G$ . Define $A + A := {a + b : a, b \in A}$ and $A ∔ A := {a + b : a, b \in A and a \neq = b}$ . Th…

A variant of Davenport's constant

R Thangadurai

Let p be a prime number. Let G be a finite abelian p-group of exponent n (written additively) and A be a non-empty subset of $] n [:= {1, 2, ..., n}$ such that elements of A are inco…

On the structure of $p$ -zero-sum free sequences and its application to a variant of Erdos--Ginzburg--Ziv theorem

W D Gao, A Panigrahi, R Thangadurai

Let $p$ be any odd prime number. Let $k$ be any positive integer such that $2 \leq k \leq [\frac{p + 1}{3}] + 1$ . Let $S = (a_{1}, a_{2}, ..., a_{2 p - k})$ be any sequence in $Z_{p}$ such that…
