Lagrangian Zigzag Cobordisms
Joshua M. Sabloff, David Shea Vela-Vick, C. -M. Michael Wong +1
We investigate an equivalence relation on Legendrian knots in the standard contact three-space defined by the existence of an interpolating zigzag of Lagrangian cobordisms. We comp…
Lagrangian cobordism of positroid links
Johan Asplund, Youngjin Bae, Orsola Capovilla-Searle +3
Casals-Gorsky-Gorsky-Simental realized all positroid strata of the complex Grassmannian as augmentation varieties of Legendrians called positroid links. We prove that the partial o…
Obstructing Lagrangian concordance for closures of 3-braids
Angela Wu
We show that any knot which is smoothly the closure of a 3-braid cannot be Lagrangian concordant to and from the maximum Thurston-Bennequin Legendrian unknot except the unknot itse…
Weinstein handlebodies for complements of smoothed toric divisors
Bahar Acu, Orsola Capovilla-Searle, Agnès Gadbled +4
We study the interactions between toric manifolds and Weinstein handlebodies. We define a partially-centered condition on a Delzant polytope, which we prove ensures that the comple…
