Legendrian representative conjecture for knots in lens spaces with 3-sphere surgeries
Legendrian representative conjecture for knots in lens spaces with 3-sphere surgeries
Let be a lens space with universally tight contact structure , and let be a knot admitting a surgery to the 3-sphere. A Legendrian representative of is a Legendrian knot representing . Legendrian nonvanishing conjecture. Every such knot has a Legendrian representative satisfying
The conjecture proposes that the Legendrian GRID invariants can detect knots in lens spaces admitting surgery to the 3-sphere, a class related by duality to the Berge conjecture and simple knots. Its status is not specified in the source.
