Topological mirror symmetry for quasi-BPS categories of Higgs bundles

Let GG be a reductive group, let LG^{L}G be its Langlands dual, and let (χ,w)π1(G)×Z(G)(\chi,w)\in\pi_1(G)\times Z(G)^{\vee}. Let TLG(w)χ\mathbb{T}_{^{L}G}(w)_{-\chi} and TG(χ)w\mathbb{T}_G(\chi)_w denote the corresponding quasi-BPS categories, with nilpotent-support subcategories defined similarly. Topological mirror symmetry conjecture. There is an equivalence

TLG(w)χTG(χ)w,\mathbb{T}_{^{L}G}(w)_{-\chi}\simeq\mathbb{T}_G(\chi)_w,

which restricts to an equivalence of the quasi-BPS categories with nilpotent singular supports. This is presented as a consequence of compatibility of the two semiorthogonal decompositions and generalizes the cited conjecture for Higgs-bundle mirror symmetry.
