“…The sum formula for FMZVs and SMZVs was conjectured by Kaneko, and proved by Saito and Wakabayashi for FMZVs [24,Theorem 1.4] and by Murahara for SMZVs [18,Theorem 1.2]. Moreover, there are several results on weighted sum formula of FMZVs, SMZVs, and their interpolation (for example, [6], [10], [16], [19], [20]). In this paper, we also prove a kind of weighted sum formula for 1/2-FMZVs and 1/2-SMZVs.…”
