On Lagrangians of Oakley-Usher type

Joé Brendel, Joé Brendel, Andrea Piccirilli

The paper constructs non‑toric Lagrangian submanifolds via symplectic reduction for non‑abelian group actions, examines their various knotting and isotopy properties, and studies m…

The spread construction and non-uniqueness of visible Lagrangians

Joé Brendel, Joé Brendel, Reto Kaufmann

The paper shows that every Hirzebruch surface contains both a Lagrangian torus and a Lagrangian Klein bottle whose images under the moment map fill the whole moment polytope, and i…

The Lagrangian flux-monodromy morphism

Joé Brendel, Joé Brendel, Jean-Philippe Chassé +3

The authors define a new morphism on the fundamental group of the space of Lagrangian submanifolds that incorporates Lagrangian flux and monodromy, study when its image is discrete…

A note on the cardinality of Lagrangian packings

Joé Brendel, Jean-Philippe Chassé, Laurent Côté

Given a symplectic manifold, can one pack uncountably many Lagrangian submanifolds in a given Hamiltonian isotopy class of this symplectic manifold? We address and

Markov staircases

Nikolas Adaloglou, Joé Brendel, Jonny Evans +2

Rational homology ellipsoids are certain Liouville domains diffeomorphic to rational homology balls and having Lagrangian pin-wheels as their skeleta. From the point of view of alm…

Lagrangian split tori in and billiards

Joé Brendel, Joontae Kim

In this paper, we classify up to Hamiltonian isotopy Lagrangian tori that split as a product of circles in , when the latter is equipped with a non-monotone split s…
