given an n-tuple of non-commutative random variables, its free stein discrepancy relative to the semicircle law measures how ​``close '' the distribution is to the semicircle law. by considering free stein discrepancies relative to a broader class of laws, one can define a quantity called the free stein information. in this talk, we will discuss this and its relation to other free probabilistic quantities such as the free fisher information and the non-microstates free entropy dimension. this is based on joint work in progress with ian charlesworth.
