The deformability condition for submanifolds of fixed degree immersed in a graded manifold can be expressed as a system of first order PDEs. In the particular but important case of ruled submanifolds. we introduce a natural choice of coordinates. which allows to deeply simplify the formal expression of the system. https://safeersappliancers.shop/product-category/siemens-gs36nvi3pg-free-standing-242-litres-a-upright-freezer-stainless-steel/
