It seems that Professor Lennart Carleson gave a series of Lectures at UCLA in 1985. For example, one could find several mentions about these lectures in the book by Garnett & Marshal (see for example, notes at the end of chapters II and III). I would like to know whether is aware of theses lectures; preferably available in electronic form?
I'm not sure about the context of these lectures; But, it seems that it was about some topics in complex analysis; potential theory; (quasi-)conformal mappings, harmonic measures and so on.
