A note on the concordance invariant epsilon
Shida Wang
We compare the smooth concordance invariants Upsilon, phi and epsilon. Previous work gave examples of knots with one of the Upsilon and phi invariants zero but the epsilon invarian…
A note on the concordance invariants Upsilon and phi
Shida Wang
Dai, Hom, Stoffregen and Truong defined a family of concordance invariants . The example of a knot with zero Upsilon invariant but nonzero epsilon invariant previously given b…
A further note on the concordance invariants epsilon and Upsilon
Shida Wang
Hom gives an example of a knot with vanishing Upsilon invariant but nonzero epsilon invariant. We build more such knots that are linearly independent in the smooth concordance grou…
The genus filtration in the smooth concordance group
Shida Wang
We define a filtration of the smooth concordance group based on the genus of representative knots. We use the Heegaard Floer epsilon and Upsilon invariants to prove the quotient gr…
On the First Singularity for the Upsilon Invariant of Algebraic Knots
Shida Wang
We show that the location of the first singularity of the Upsilon function of an algebraic knot is determined by the first term of its Puiseux characteristic sequence. In many case…
