ABSTRACT Let ? be a hyperbolic Kac–Moody algebra of rank 2, and set , where are the fundamental weights for ?; note that λ is neither dominant nor antidominant. Let ?(λ) be the crystal of all Lakshmibai–Seshadri paths of shape λ. We prove that (the crystal graph of) ?(λ) is connected. Furthermore, we give an explicit description of Lakshmibai–Seshadri paths of shape λ.
