A Coxeter diagram encodes reflection symmetries of a configuration-space tiling. In the construction considered here, diagrams without bifurcations can potentially generate solvabl…
A kaleidoscope is a system of mirrors in which none of the multiple images of an object is broken at a mirror junction. Exactly solvable one-dimensional few-body problems can arise…
Let be the Hamiltonian of particles in the setting of --, with all pair potentials bounded and of finite range. Suppose … that the pair…
