Abstract

We define the notion of a weighted unfolding of quivers with real weights, and use this to provide a categorification of mutations of quivers of finite types H4H_4, H3H_3 and I2(2n+1)I_2(2n+1). In particular, the (un)folding induces a semiring action on the categories associated to the unfolded quivers of types E8E_8, D6D_6 and A2nA_{2n} respectively. We then define the tropical seed pattern on the folded quivers, which includes cc- and gg-vectors, and show its compatibility with the unfolding.
