The BPS Lie algebra conjecture for symmetric quivers with potential

Less than 1 year old · traced to

Let QQ be a symmetric quiver with potential W\mathsf{W}. Let gQ,W\mathfrak{g}_{Q,\mathsf{W}} be the Lie superalgebra defined from the classical RR-matrix, and write

gQ,W+=⨁η>0gη.\mathfrak{g}^+_{Q,\mathsf{W}}=\bigoplus_{\eta>0}\mathfrak{g}_{\eta}.

The positive part of gQ,W\mathfrak{g}_{Q,\mathsf{W}} should be identified with the BPS Lie algebra of Davison--Meinhardt. BPS Lie algebra conjecture. There is a C(t0)\mathbb{C}(\mathsf t_0)-Lie algebra isomorphism

gQ,W+≅gQ,WBPS,T0⊗C[t0]C(t0)\mathfrak{g}^+_{Q,\mathsf{W}}\cong \mathfrak{g}^{\mathrm{BPS},\mathsf T_0}_{Q,\mathsf{W}}\otimes_{\mathbb{C}[\mathsf t_0]}\mathbb{C}(\mathsf t_0)

that intertwines their actions on any state space Hd‾,AfrWfr\mathcal{H}^{\mathsf{W}^{\mathrm{fr}}}_{\underline{\mathbf{d}},\mathsf A^{\mathrm{fr}}}. This is the proposed comparison between the classical RR-matrix Lie algebra and the lowest perverse component of the CoHA; the analogous identification for tripled quivers with canonical cubic potential is known, while the general case remains open.
