AT-algebras from zero-dimensional dynamical systems

Herstedt, Paul (University of Oregon, 2020-09-24)

We outline a particular type of zero-dimensional system (which we call "fiberwise essentially minimal"), which, together with the condition of all points being aperiodic, guarantee that the associated crossed product ...
Manifolds with indefinite metrics whose skew-symmetric curvature operator has constant eigenvalues

Zhang, Tan, 1969- (University of Oregon, 2000)

Relative to a non-degenerate metric of signature (p, q), an algebraic curvature tensor is said to be IP if the associated skew-symmetric curvature operator R(π) has constant eigenvalues and if the kernel of R(π) has constant ...
