WebThe theorem states that you can unknot the rope without moving the lightbulb. This principle has been demonstrated for 3-dimensional space but has only been recently shown to be true for 4-dimensional space as well. The formal statement of the 4-dimensional light bulb follows below. The 4-dimensional light bulb theorem: WebAbstract: The 4-dimensional light bulb theorem asserts that a smooth 2-sphere in S 2 × S 2 that is homotopic to point × S 2 and intersects a S 2 × point transversely once is smoothly …
