BV bialgebra structures in Floer theory and string topology
Janko Latschev, Alexandru Oancea
We derive the notions of BV unital infinitesimal bialgebra and BV Frobenius algebra from the topology of suitable compactifications of moduli spaces of decorated genus 0 curves. We…
Remarks on the rational SFT formalism
Janko Latschev
Recent work of Siegel and of Moreno and Zhou uses rational symplectic field theory to construct (different) invariants of contact manifolds. Here, I review how the algebraic parts…
Knot contact homology, string topology, and the cord algebra
Kai Cieliebak, Tobias Ekholm, Janko Latschev +1
The conormal Lagrangian of a knot in is the submanifold of the cotangent bundle consisting of covectors along that annihilate tangen…
Fukaya's work on Lagrangian embeddings
Janko Latschev
This is an expository account of some applications of string topology to the study of Lagrangian embeddings into symplectic manifolds, originally due to Fukaya, which was written a…
The Gromov width of 4-dimensional tori
Janko Latschev, Dusa McDuff, Felix Schlenk
We show that every 4-dimensional torus with a linear symplectic form can be fully filled by one symplectic ball. If such a torus is not symplectomorphic to a product of 2-dimension…
Algebraic Torsion in Contact Manifolds
Janko Latschev, Chris Wendl
We extract a nonnegative integer-valued invariant, which we call the "order of algebraic torsion", from the Symplectic Field Theory of a closed contact manifold, and show that its…
