Pseudo-holomorphic triangles and the median quasi-state

Pazit Haim-Kislev, Michael Khanevsky, Asaf Kislev +1

We prove that the minimal area of a holomorphic triangle whose boundary lies on the union of any three Lagrangian submanifolds is bounded from above by the Lagrangian spectral norm…

Hofer's distance between eggbeaters and autonomous Hamiltonian diffeomorphisms on surfaces

Michael Khanevsky

Let be a compact surface of genus equipped with an area form. We construct eggbeater Hamiltonian diffeomorphisms which lie arbitrarily far in the Hofer metric from t…

A gap in the Hofer metric between integrable and autonomous Hamiltonian diffeomorphisms on surfaces

Michael Khanevsky

Let be a compact surface equipped with an area form. There is an long standing open question by Katok, which, in particular, asks whether every entropy-zero Hamiltonian diffeom…

Curve obstruction for autonomous diffeomorphisms on surfaces

Michael Khanevsky

Consider a Hamiltonian diffeomorphism on a surface. We describe several scenarios where a curve and its image provide a simple evidence that is not autonomous.

Quasimorphisms on surfaces and continuity in the Hofer norm

Michael Khanevsky

There is a number of known constructions of quasimorphisms on Hamiltonian groups. We show that on surfaces many of these quasimorphisms are not compatible with the Hofer norm in a…

A Floer-Gysin exact sequence for Lagrangian submanifolds

Paul Biran, Michael Khanevsky

In this paper we establish a Floer-theoretical analog of the classical Gysin long exact sequence from algebraic topology for circle bundles. We study algebraic and functorial prope…
