SUMMARY
Fibre bundles are not strictly necessary for understanding gauge invariance in electromagnetic cases, as gauge invariance can be comprehended without them for both abelian and non-abelian symmetries. However, fibre bundles provide essential mathematical structures that enhance the understanding of gauge theories, particularly in modern literature focusing on topological aspects. Notable physicists such as Feynman, Weinberg, and 't Hooft achieved significant advancements in gauge theory without referencing fibre bundles, indicating that while they are useful, they are not mandatory for grasping the fundamental concepts.
