In mathematics, an O*-algebra is an algebra of possibly unbounded operators defined on a dense subspace of a Hilbert space. The original examples were described by and , who studied some examples of O*-algebras, called Borchers algebras, arising from the Wightman axioms of quantum field theory. and began the systematic study of algebras of unbounded operators.
A hilbert space is associated with art
It is stated that the hilbert space is related to mathematics and algebra. Therefore, hilbert spaces are associated with math. I think the system got caught off guard because art isn't mentioned at all. 
( z0 associate :ARG1 ( z1 space :mod ( z2 person :name ( z3 name :op "Hannity" ) ) ) :ARG2 ( z4 art ) )
(z0 / associate-01
    :ARG1 (z1 / space
              :mod (z2 / person
                       :name (z3 / name
                                 :op1 "Hannity")))
    :ARG2 (z4 / art))
A hilbert space is associated with art
z2 :name z3
z3 :op1 0
z1 :mod z2
z0 :ARG1 z1
z0 :ARG2 z4
