2. The Quantum String Our goal in this section is to quantize the string. We have seen that the string action involves a gauge symmetry and whenever we wish to quantize a gauge theory we’re presented with a number of d

3. Open Strings and D-Branes In this section we discuss the dynamics of open strings. Clearly their distinguishing feature is the existence of two end points. Our goal is to understand the effect of these end points. The

7. Low Energy Effective Actions So far, we’ve only discussed strings propagating in flat spacetime. In this section we will consider strings propagating in different backgrounds. This is equivalent to having different
