We study the problem of giving bounds on the largest positive integer $n$ that is locally represented by $Q$ but not represented. Assuming that $n$ is relatively prime to $D(Q)$, the determinant o...

In this article, we discusscongruences sat...

If $F$ is CM and the Brumer–Stark conjecture holds for $F/K$, we construct a family of $G(F/K)$-equivariant Hecke characters for $F$ with infinite type equal to a spec...

From their works, we know a countable collection of points in $M\setminus L$.;;In this article, we describe the str...

The cuspidal divisor class group $\mathfrak{C}^+...  作者：C. Miguel 来源：[J].Acta Arithmetica(IF 0.472), 2019, Vol.188, pp.317-324IMPAS 摘要：For a finite commutative ring$R$with identity, we obtain an exact formula for the number of ways to represent each element of$R$as the sum of two exceptional units. This generalizes to finite rings a recent result of J. W. Sander for the ring$\mathbb Z_n$of residue classes ...  作者：László Mérai , Igor E.

Our approach yields exact formulas for this quantity, which measures the irregularities of distribution of a set of points in the unit interval. We obtain such formu...
