  On the fiftieth anniversary of Yang-Mills theory, I review the contribution
to its understanding by my collaborators and me. Contents: 1.Gauge Theories and
Quantum Anomalies; 2.Mathematical Connections; 3. Gauge Field Dynamics other
than Yang-Mills; 4. Gauge Formalism for General Relativity Variables; A.
Christoffel connection as a gauge potential, B. Gravitational Chern-Simons term
from gauge theory Chern-Simons term, C. Coordinate transformations in general
relativity and gauge theory, (i) Response to changes in coordinates (ii)
Invariant fields and constants of motion. References.
