    Abstract

    We define invariants for colored oriented spatial graphs by generalizing CM invariants [F. Costantino and J. Murakami, On SL(2,C) quantum 6j-symbols and their relation to the hyperbolic volume, Quantum Topol. 4 (2013) 303-351], which were defined via non-integral highest weight representations of q(sl2). We apply the same method used to define Yokota's invariants, and we call these invariants Yokota type invariants. Then, we propose a volume conjecture of the Yokota type invariants of plane graphs, which relates to volumes of hyperbolic polyhedra corresponding to the graphs, and check it numerically for some square pyramids and pentagonal pyramids.
