Abstract:
We show that inside a trivial open book $\partial (W\times D^2)$ with page being a Weinstein manifold $(W, d\theta)$, any Legendrian which is contained entirely inside a page and which intersects some cocore disc transversely in a single point is loose. This leads to the alternative proof of Casals-Murphy criterion of looseness. This is joint work with Georgios Dimitroglou Rizell.
