Abstract: | This paper is devoted to the asymptotic analysis of functions depending on a small parameter characterizing the microinhomogeneous structure of the domain on which the functions are defined. We derive the Friedrichs inequality for these functions and prove the convergence of solutions to corresponding problems posed in a domain perforated aperiodically along the boundary. Moreover, we use numerical simulation to illustrate the results. The work of the first author was partially supported by RFBR. The work of the first and the second authors was partially supported by the program “Leading Scientific Schools” (NSh-1698.2008.1). |
