   Exterior Derivative and Gauge Theory
   In theoretical physics, particularly in Yang-Mills theories, the exterior derivative is augmented to become the exterior covariant derivative, $D$. If $\omega$ represents a gauge potential (a 1-form connection), the field strength tensor $F$ (curvature) is defined as:
   $$F = D\omega = \text{d}\omega + \omega \wedge \omega$$
   Here, the second term,…
