Equivalencies of two-dimensional CFT models and relations between quantum field theories in different space-time dimensions

Rich symmetry present in two-dimensional world often allows to relate apparently quite different, quantum models. I will discuss two examples of such equivalences (both involving quantum, two-dimensional gravity with cosmological constant, i.e. Liouville field theory) and show their relevance for understanding the Alday-Gaiotto-Tachikawa relation between two-dimensional conformal models and the moduli space of instantons in four-dimensional, supersymmetric gauge theories.
