The object of the present work is to study the quantum Hall effect through its symmetries and topological aspects. We consider the model of an electron moving in a two‐dimensional lattice in the presence of applied in‐plain electric field and perpendicular magnetic field. We refer to this as the two dimensional electric–magnetic Bloch problem (EMB). The Hall conductivity quantization beyond the linear response approximation is analyzed.
