@user @user The gauge potential is the connection on the quantum field as like in differential geometry. and the field strength  tensor is the curvature tensor.

@user @userEl potencial del medidor es la conexión en el campo cuántico como en la geometría diferencial.Y el tensor de fuerza del campo es el tensor de curvatura.
