We investigate the invertible and non-invertible symmetries of topological finite-group gauge theories in general spacetime dimensions. where the gauge group can be abelian or non-abelian. We focus in particular on the 0-form symmetry. The gapped domain walls that generate these symmetries are specified by boundary conditions for the gauge fields on either side of the wall. https://herbsdailyes.shop/product-category/suction-instruments/
