In particular, I’ll describe the Kaluza-Klein reduction procedure, basic facts about Calabi-Yau manifolds and why they are important in string theory, effective actions arising in the low energy limit, their moduli spaces, their symmetries and dualities between them. Depending on time, I may also touch the problem of quantum corrections and compactifications with fluxes. %G English %L hal-02046929 %U https://hal.science/hal-02046929 %~ CNRS %~ L2C %~ MIPS %~ UNIV-MONTPELLIER %~ UM-2015-2021
