## Worst scenario method in homogenization. Linear case.(English)Zbl 1164.35317

Summary: The paper deals with homogenization of a linear elliptic boundary problem with a specific class of uncertain coefficients describing composite materials with periodic structure. Instead of the stochastic approach to the problem, we use the worst scenario method due to I. Hlaváček (method of reliable solution). A few criterion functionals are introduced. We focus on the range of the homogenized coefficients from knowledge of the ranges of individual components in the composite, on the values of the generalized gradient in the places where these components change and on the average of the homogenized solution in some critical subdomain.
