Properties of contact toric structures and concave boundaries of linear plumbings
Aleksandra Marinković, Jo Nelson, Ana Rechtman +3
We consider plumbings of symplectic disk bundles over spheres admitting concave contact boundary, with the goal of understanding the geometric properties of the boundary contact st…
