Lagrangian product tori in tame symplectic manifolds
Yuri Chekanov, Felix Schlenk
Product Lagrangian tori in standard symplectic space were classified up to symplectomorphism in [Che96]. We extend this classification to tame symplectically aspherical sy…
Notes on monotone Lagrangian twist tori
Yuri Chekanov, Felix Schlenk
We construct monotone Lagrangian tori in the standard symplectic vector space, in the complex projective space and in products of spheres. We explain how to classify these Lagrangi…
Minimal atlases of closed contact manifolds
Yuri Chekanov, Otto van Koert, Felix Schlenk
We study the minimal number C(M,ξ) of contact charts that one needs to cover a closed connected contact manifold (M,ξ). Our basic result is C(M,ξ) \le \dim M + 1. We compute C(M,ξ)…
Invariants of Legendrian knots
Yuri Chekanov
We present two different constructions of invariants for Legendrian knots in the standard contact space . These invariants are defined combinatorially, in terms of certain pl…
Differential algebras of Legendrian links
Yuri Chekanov
The problem of classification of Legendrian knots (links) up to isotopy in the class of Legendrian embeddings (Legendrian isotopy) naturally leads to the following two subproblems.…
