Membership in moment polytopes is in NP and coNP
Peter Bürgisser, Matthias Christandl, Ketan D. Mulmuley +1
We show that the problem of deciding membership in the moment polytope associated with a finite-dimensional unitary representation of a compact, connected Lie group is in NP and co…
Holographic entropy inequalities and gapped phases of matter
Ning Bao, ChunJun Cao, Michael Walter +1
We extend our studies of holographic entropy inequalities to gapped phases of matter. For any number of regions, we determine the linear entropy inequalities satisfied by systems i…
On vanishing of Kronecker coefficients
Christian Ikenmeyer, Ketan D. Mulmuley, Michael Walter
We show that the problem of deciding positivity of Kronecker coefficients is NP-hard. Previously, this problem was conjectured to be in P, just as for the Littlewood-Richardson coe…
The Holographic Entropy Cone
Ning Bao, Sepehr Nezami, Hirosi Ooguri +3
We initiate a systematic enumeration and classification of entropy inequalities satisfied by the Ryu-Takayanagi formula for conformal field theory states with smooth holographic du…
