Abstract

Let x x be an element of a finite group G G and denote the order of x x by ord(x) \mathrm{ord}(x) . We consider a finite group G G such that gcd(ord(x),ord(y))2 \gcd(\mathrm{ord}(x),\mathrm{ord}(y))\leqslant 2 for any two vanishing elements x x and y y contained in distinct conjugacy classes. We show that such a group G G is solvable. When G G with the property above is supersolvable, we show that G G has a normal metabelian 2 2 -complement.
