The main topic which I plan to cover in these lectures is the contributions of electromagnetic and weak interactions to the divergence of the hadron currents. The corresponding divergence equations lead to an alternative approach to the well known method of current algebra and can be shown to imply equal-time current-current commutators. You may wonder then why we should consider this topic, in particular since the equivalence to the conventional approach can be demonstrated. One reason is that we are trying to extend these ideas to include dynamics of the hadrons and it is not a priori clear which view point leads more readily to useful generalization. Another reason is that the divergence method sheds light on certain confusion which has arisen in connection with the singular behaviour of equal time commutators of currents, the so-called Schwinger term.
