We consider ''geometric'' scattering for a Laplace᎐Beltrami operator on a compact Riemannian manifold inserted between ''wires,'' that is, two half-lines. We discuss applicability and correctness of this model. With an example, we show that such a scattering problem may exhibit unusual properties: t

## Abstract The __d__‐distance face chromatic number of a connected plane graph is the minimum number of colors in such a coloring of its faces that whenever two distinct faces are at the distance at most __d__, they receive distinct colors. We estimate 1‐distance chromatic number for connected 4‐r
