Abstract:
By the "lightbulb theorem" I mean the result that a knot of ${S^1}$ in ${S^1} \times {S^2}$ which meets some ${S^2}$ factor in a single transverse point is isotopic to an ${S^1}$ factor. We prove an analogous result for knots of ${S^n}$ in ${S^n} \times {S^2}$, and apply it to answer a question of Rolfsen concerning PL I-equivalence of links.References
