Yurinsky, V. V. Localization of spectrum bottom for the Stokes operator in a random porous medium. (English. Russian original) Zbl 0970.35102 Sib. Math. J. 42, No. 2, 386-413 (2001); translation from Sib. Mat. Zh. 42, No. 2, 451-483 (2001). The article is devoted to the spectral theory for the Stokes operator in a random porous medium. The author exposes a series of theorems which assert that the principal eigenvalue of the Stokes system \[ \Delta U - \nabla p + f = 0,\quad \nabla\cdot U = 0 \] on a random subdomain of a cube with edge \(r\) has the order \(O(\ln^{-2/d}r)\) with probability arbitrarily close to unity. A determinate interval is also indicated which contains this random variable with probability arbitrarily close to unity.
