On the Upsilon invariant of fibered knots and right-veering open books
On the Upsilon invariant of fibered knots and right-veering open books
Ozsvath, Stipsicz and Szabo define a one-parameter family {Ļį“(t)}tā[ā,ā] of Heegaard Floer knot invariants for knots K ā SĀ³ . We generalize Ļį“ (t) to knots in any rational homology sphere. We study the Ļāinvariant of a fibered knot. We prove that the Ļāinvariant can never reach its minimum slope ā¦
