On non-vanishing elements in finite groups

‎Let $G$ be a finite group‎. ‎We denote by $\text{Van}(G)$ the set of vanishing elements of $G$‎, ‎in which an element $g$ in $G$ is vanishing element if there exists some irreducible character $\chi$ of $G$ such that $\chi(g)=0$‎. ‎In this paper‎, ‎we study some influences the structure of $G-Van(G)$ on the structure of $G$‎
