+ | **Mirror Lagrangians to lines in P^3** | ||
+ | |||
+ | We discuss work in progress in which we construct, for any tropical curve in $R^n$ with vertices of valence at most $4$, a Lagrangian submanifold of $(C^*)^n$ whose moment map projection is a tropical amoeba. These Lagrangians will have singular points modeled on the Harvey-Lawson cone over a $2$-torus. We also consider a certain $4$-valent tropical curve in $R^3$, for which we can modify the singular Lagrangian lift to obtain a cleanly immersed Lagrangian. The objects of the wrapped Fukaya category supported on this Lagrangian correspond, under mirror symmetry, to lines in $CP^3$. If time permits, we will explain how to use functors induced by Lagrangian correspondences to see this mirror relation. | ||

+ | A real 3-manifold is a smooth 3-manifold together with an orientation preserving smooth involution, called a real structure. | ||
+ | A real contact 3-manifold is a real 3-manifold with a contact distribution that is antisymmetric with respect to the real structure. | ||

+ | We show that every real contact 3-manifold can be obtained via contact surgery along invariant knots starting from the standard real contact 3-sphere. | ||
