All summer programs I know for high-school students focuses on number theory, combinatorics, graph theory, logic, and all kinds of topics in discrete mathematics. (I am mainly interested in UK, US, Canada. Any summer program that uses English Language.)
Can anyone recommend some more continuous summer programs? That is to say, are there summer schools that offers course in Analysis, Abstract algebra, Topology, and/or set theory? I am also interested in special functions, like $\Gamma$, $\Theta$ and $\zeta$ functions and elliptic integrals: just things more closely related to undergraduate level study.
