Abstract
Unitary invertible graphs of finite rings
Highlights
Let R be a finite commutative ring with unity
In general φ(Zn) is even, we demonstrate that φ(R) is odd for any finite commutative ring with unity of Char(R) = 2
We present unitary invertible graph related with self and mutual additive inverses of group units
Summary
Let R be a finite commutative ring with unity.
