quantum mechanics - Dyson series derivation



idUI(t,ti)dt=ˆVI(t)ˆUI(t,ti) The solutions of this equation, with the initial condition ˆUI(ti,ti), are given by the integral equation ˆUI(t,ti)=1ittiˆVI(t)ˆUI(t,ti)dt



In the derivation of Dyson Series please explain why in equation (10.33) t is changed to t without integrating.

classical mechanics - Moment of a force about a given axis (Torque) - Scalar or vectorial?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
