Abstract The quiver Yangians were originally defined for the quiver and superpotential from string theory on general toric Calabi-Yau threefolds. and serve as BPS algebras of these systems. Their characters reproduce the unrefined BPS indices. which are related to classical Donaldson-Thomas (DT) invariants. https://www.lecoureures.shop/product-category/ski-de-fond-accessoires-fartage/
