... versions of diffeomorphism groups.c In the case of a multimatrix model, the group
is, roughly speaking, an automorphism group of a tensor algebra. The Lie algebra
is a Cuntz-type algebra which can be thought of as an algebra of vector fields
on a noncommutative space.12,5,6,13,14 However, it is stil ...
