书目名称 | G-Convergence and Homogenization of Nonlinear Partial Differential Operators | 编辑 | Alexander Pankov | 视频video | | 丛书名称 | Mathematics and Its Applications | 图书封面 |  | 描述 | Various applications of the homogenization theory of partial differential equations resulted in the further development of this branch of mathematics, attracting an increasing interest of both mathematicians and experts in other fields. In general, the theory deals with the following: Let Ak be a sequence of differential operators, linear or nonlinepr. We want to examine the asymptotic behaviour of solutions uk to the equation Auk = f, as k ~ =, provided coefficients of Ak contain rapid oscillations. This is the case, e. g. when the coefficients are of the form a(e/x), where the function a(y) is periodic and ek ~ 0 ask~=. Of course, of oscillation, like almost periodic or random homogeneous, are of many other kinds interest as well. It seems a good idea to find a differential operator A such that uk ~ u, where u is a solution of the limit equation Au = f Such a limit operator is usually called the homogenized operator for the sequence Ak . Sometimes, the term "averaged" is used instead of "homogenized". Let us look more closely what kind of convergence one can expect for uk. Usually, we have some a priori bound for the solutions. However, due to the rapid oscillations of the coeffi | 出版日期 | Book 1997 | 关键词 | DEX; Scheme; Volume; convergence; differential equation; differential operator; equation; form; homogenizati | 版次 | 1 | doi | https://doi.org/10.1007/978-94-015-8957-4 | isbn_softcover | 978-90-481-4900-1 | isbn_ebook | 978-94-015-8957-4 | copyright | Springer Science+Business Media Dordrecht 1997 |
