| アブストラクト: |
I propose a new path integral formulation of one-particle quantum mechanics on equilateral quantum wire junctions. I find that scale-invariant junctions realized at fixed points of boundary renormalization group flow are in one-to-one correspondence with matrix-valued weight factors on the path integral side. I show that these weight factors are generally given by multi-dimensional unitary representations of the infinite dihedral group.
