Quand seule la sous-somme vide est nulle modulo $p$

Jean-Marc Deshouillers (2007)

Journal de Théorie des Nombres de Bordeaux

Soit $c > 1$ , $p$ un nombre premier et $𝒜$ une partie de $ℤ / p ℤ$ de cardinal supérieur à $c \sqrt{p}$ telle que pour tout sous-ensemble non vide $ℬ$ de $𝒜$ , on a $\sum_{b \in ℬ} b \neq 0$ . On montre qu’il existe $s$ premier à $p$ tel que l’ensemble $s . 𝒜$ est très concentré autour de l’origine et qu’il est presque entièrement composé d’éléments de partie fractionnaire positive. Plus précisément, on a $\sum_{a \in 𝒜} ∥\frac{s a}{p}∥ < 1 + O (p^{- 1 / 4} ln p) et \sum_{\begin{matrix} a \in 𝒜, \\ {s a / p} \geq 1 / 2 \end{matrix}} ∥\frac{s a}{p}∥ = O (p^{- 1 / 4} ln p) .$ On montre également que les termes d’erreurs ne peuvent être remplacés par $o (p^{- 1 / 2})$ .

Recognition of characteristically simple group $A_{5} \times A_{5}$ by character degree graph and order

Maryam Khademi, Behrooz Khosravi (2018)

Czechoslovak Mathematical Journal

The character degree graph of a finite group $G$ is the graph whose vertices are the prime divisors of the irreducible character degrees of $G$ and two vertices $p$ and $q$ are joined by an edge if $p q$ divides some irreducible character degree of $G$ . It is proved that some simple groups are uniquely determined by their orders and their character degree graphs. But since the character degree graphs of the characteristically simple groups are complete, there are very narrow class of characteristically simple...
