Abstract We study half-BPS surface operators in supersymmetric gauge theories in four and five dimensions following two different approaches. In the first approach we analyze the chiral ring equations for certain quiver theories in two and three dimensions. coupled respectively to four- and five-dimensional gauge theories. The chiral ring equations. https://safeersappliancers.shop/product-category/bosch-cma585gs0b-serie-6-900-watt-microwave-built-in-stainless-steel/
