Equivariant semidefinite lifts of regular polygons
(Institute for Operations Research and the Management SciencesMathematics of Operations Research, 2017-05-01)
Given a polytope P in $\mathbb{R}^n$, we say that P has a positive
semidefinite lift (psd lift) of size d if one can express P as the linear
projection of an affine slice of the positive semidefinite cone
$\mathbf{S}^d_+$. ...
