### Boundaries of amplituhedra and NMHV symbol alphabets at two loops

In this sequel to [3] we classify the boundaries of amplituhedra relevant for determining the branch points of general two-loop amplitudes in planar N=4$$\mathcal{N}=4$$ super-Yang-Mills theory. We explain the connection to on-shell diagrams, which serves as a useful cross-check. We determine the...
