Spatial motive mechanism and integrative development mode of Hohhot-Baotou-Ordos region
We took the Hohhot-Baotou-Ordos cities group as the study object to analyze the existing status and problems of the Hohhot-Baotou-Ordos region's integrative development,and discuss the spatial motive mechanism and suitable development mode for the Hohhot-Baotou-Ordos region,so that to find out theoretic support,development route,as well as polices and countermeasures etc for the healthy integrative development of the Hohhot-Baotou-Ordos region,and expedite the economic development of the Hohhot-Baotou-Ordos region,so that to more efficiently promote the spatial development of the surrounding districts and boost the process of regional development and planning of our country.
We deal with linear parabolic (in the sense ::: of Petrovskii) systems of order $2b$ with discontinuous principal ::: coefficients. A priori estimates in Sobolev and ::: Sobolev--Morrey spaces are proved for the strong solutions by ::: means of potential analysis and boundedness of certain singular ::: integral operators with kernels of mixed homogeneity. As a ::: byproduct, precise characterization of the Morrey, $BMO$ and ::: Holder regularity is given for the solutions and their ::: derivatives up to order $2b-1.$
