Nodal Domains on Surfaces under Perturbation: Upper Semicontinuity, Courant-Sharpness, and Boundary Intersections

Saikat Maji, Mayukh Mukherjee, Soumyajit Saha

We study how the number of nodal domains of eigenfunctions of Schrödinger operators $- Δ_{g_{t}} + V_{t}$ on closed surfaces changes under smooth perturbations of $(g_{t}, V_{t})$ along conver…
