A holographic inequality for N = 7 regions

A bstract In holographic duality, boundary states that have semiclassical bulk duals must obey inequalities, which bound their subsystems’ von Neumann entropies. Hitherto known inequalities constrain entropies of reduced on up to N = 5 disjoint subsystems. Here we report one new such inequality, involves 7 regions. Our work supports a recent conjecture the structure predicted existence and schematic form inequality. We explain logic educated guesses by arrived at comment feasibility employing similar tactics in more exhaustive search.
