In the light of the decomposition of the 𝑆𝑈 (2) gauge potential for 𝐼 = 1/2, we obtain the 𝑆𝑈 (2) Chern-Simons current over 𝑆 4 , i.e. the vortex current in the effective field for the four-dimensional quantum Hall effect. Similar to the vortex excitations in the two-dimensional quantum Hall effect (2D FQH) which are generated from the zero points of the complex scalar field, in the 4D FQH, we show that the 𝑆𝑈 (2) Chern-Simons vortices are generated from the zero points of the two-component wave functions Ψ, and their topological charges are quantized in terms of the Hopf indices and Brouwer degrees of 𝜑-mapping under the condition that the zero points of field Ψ are regular points.
