Title: Sigma-convergence of stationary Navier-Stokes type equations Authors: Gabriel Nguetseng (Univ. of Yaounde 1, Cameroon) Lazarus Signing (Univ. of Ngaoundere, Cameroon) Abstract: In the framework of homogenization theory, the Sigma-convergence method is carried out on stationary Navier-Stokes type equations on a fixed domain. Our main tools are the two-scale convergence concept and the so-called homogenization algebras. Submitted February 03, 2009. Published June 05, 2009. Math Subject Classifications: 35B40, 46J10.
