There is information about study in the faculty of Mathematics on the DAMTP home page.
Aside from a small portion of the Part II (i.e. third year) Waves course, there are currently no courses in solid mechanics offered in DAMTP. However, the Mathematical Methods, Complex Analysis/Methods and Continuum Mechanics courses are relevant. As the group grows, it is likely that the Master of Mathematics (aka Part III) will offers courses related to our work.
