Webthe rst global existence of smooth embeddings was given by Nash [22], but the best result as of this time is the following theorem of Gun ther [14]: Any smooth d-dimensional compact Riemannian manifold admits a smooth (i.e. C1) isometric embedding in RN for N= 1 2 maxfd(d+5);d(d+3)+10g. Needless to say, it is of considerable interest to know if WebNash [23]. De Giorgi’s argument was later simplified by Moser [18]. The key H¨older estimates have also been generalized to parabolic equations of non-divergence form by Krylov and Safanov [11], Aronson [2] and other mathematicians, and thus have become a standard tool called De Giorgi-Nash-Moser iteration.

WebUPC Universitat Politècnica de Catalunya WebNash-Moser iteration is a powerful tool which requires only a family of so-called tame estimates [5] for the linearized problems. In such cases, the order for the ap-proximate solution could be much higher than the smoothness order of the required solution. Given the initial-boundary data which are compatible up to any order, then
