BMO and Asymptotic Homogeneity
نویسندگان
چکیده
First, we prove that the BMO condition by John–Nirenberg leads in natural way to asymptotic homogeneity at origin of regular homeomorphic solutions degenerate Beltrami equations. Then, on this basis establish a series criteria for existence equations whole complex plane with infinity. These results can be applied fluid mechanics strongly anisotropic and inhomogeneous media because equation is form main hydromechanics.

متن کاملBMO is the intersection of two translates of dyadic BMO
Let T be the unit circle on R2. Denote by BMO(T) the classical BMO space and denote by BMOD(T) the usual dyadic BMO space on T. Then, for suitably chosen δ ∈R, we have ‖φ‖BMO(T) ‖φ‖BMOD(T) + ‖φ(· − 2δπ)‖BMOD(T), ∀φ ∈ BMO(T). To cite this article: T. Mei, C. R. Acad. Sci. Paris, Ser. I 336 (2003). 2003 Académie des sciences.

چکیده: فرض کنید که تابعی از اپسیلون یک مجموع نامتناهی از احتمالات موزون مربوط به مجموع های جزئی براساس یک دنباله از متغیرهای تصادفی مستقل و همتوزیع باشد، و همچنین فرض کنید توابعی مانند g و h وجود دارند که هرگاه امید ریاضی توان دوم x متناهی و امیدریاضی x صفر باشد، در این صورت می توان حد حاصلضرب این توابع را بصورت تابعی از امید ریاضی توان دوم x نوشت. حالت عکس نیز برقرار است. همچنین ما با استفاده...

متن کاملFunctional Calculus on BMO and related spaces
Let f be a Borel measurable function of the complex plane to itself. We consider the nonlinear operator Tf defined by Tf [g] = f ◦ g, when g belongs to a certain subspace X of the space BMO(Rn) of functions with bounded mean oscillation on the Euclidean space. In particular, we investigate the case in which X is the whole of BMO, the case in which X is the space VMO of functions with vanishing ...
