Abstract: We define spectral set, complete spectral set and rational dilation and study rational dilation of commuting operator tuples associated with various domains in $\mathbb C^n$. We discuss representations of distinguished varieties in several families of domains and find conditions under which von Neumann's inequality holds on such sets.
