In this talk I will present the lattices of subobjects and quotients which appear in the theory of coalgebras, bialgebras and Hopf algebras, and their actions/coactions on rings. Apart of their basic properties, if time permits, I will present a Galois theory for H-comodule algebras which led to these lattice theoretic considerations.
