An unofficial class (hence the name) for advanced students in physics and math to learn nonrelativistic quantum mechanics in a mathematically rigorous fashion.The material is at the upper-division undergraduate level and requires a thorough command of single-variable calculus, as well as willingness to learn more advanced mathematical topics.The class is not for credit and is only for those who are interested in learning about the subject in more detail.(A less rigorous treatment, which focuses on the cool results, can be found in Modern Physics.)
