Polyakov's Lectures on String Theory
These lectures were given by Professor Alexander Polyakov when he taught a graduate course on String Theory at Princeton in the fall semesters of 2013 and 2014. Vladimir Kirilin, a student in the class, reviewed the videos and provided the notes below. Grigory Tarnopolskiy, also a student in the class, took notes in 2013 and 2014. Some of the lectures follow material presented in Polakov's "Gauge Fields and Strings" (Mathematical Reports, 1987). The lectures are presented here for your enjoyment.
The files are 0.5-1.0 GB in MP4 format. If your browser is setup with proper A/V player, a lecture will start playing in a separate window immediately. If you are connecting to a low bandwidth or congested network, you might see some artifacts in the videos. If it happens too frequently, you may download the whole file on your local disk and play it offline. The first two lectures in 2013 were not recorded well and so we have substituted in two similar lectures from the fall of 2014. We apologize that the first half sentence is missing from some of these videos. We hope Tarnopolskiy's notes can resolve any questions.
