摘要 | This paper considers a generalization of the "max-cut-polytope" conv{xxT divide x is an element of Rn,|xk|=1for1 <= k <= n}in the space of real symmetric nxnmatrices with all-one diagonal to a complex "unit modulus lifting" conv{xx* divide x is an element of Cn,|xk|=1for1 <= k <= n}in the space of complex Hermitian nxn-matrices with all-one diagonal. The unit modulus lifting arises in applications such as digital communications and shares similar symmetry properties as the max-cut-polytope. Set-completely positive representations of both sets are derived and the relation of the complex unit modulus lifting to its semidefinite relaxation is investigated in dimensions 3 and 4. It is shown that the unit modulus lifting coincides with its semidefinite relaxation in dimension 3 but not in dimension 4. In dimension 4 a family of deep valid cuts for the unit modulus lifting is derived that could be used to strengthen the semidefinite relaxation. It turns out that the deep cuts are also implied by a second lifting that could be used alternatively. Numerical experiments are presented comparing the first lifting, the second lifting, and the unit modulus lifting for n=4. |
