Full algebras and spectral equality

In this paper; consideration is given to the full algebras. Following this, we have shown that the equality $\sigma_A(a)0\sigma_B(\Phi(a))$ = is satisfied when A, B are semisimple, regular, commutative Banach algebra with identity, Banach algebra with identity respectively.
