Abstract We systematically study the master space of brane brick models that represent a large class of 2d (0. 2) quiver gauge theories. These 2d (0. 2) theories are worldvolume theories of D1-branes that probe singular toric Calabi-Yau 4-folds. https://www.countryscenesaddleryandpetsuppliers.shop/product-category/halter/
