Homogenization of a Periodic Parabolic Cauchy Problem in the Sobolev Space (ℝ)
In (ℝ; ℂ), we consider a wide class of matrix elliptic second order differential operators with rapidly oscillating coefficients (depending on /). For a fixed > 0 and small > 0, we find approximation of the operator exponential exp(− ) in the ( (ℝ; ℂ) → (ℝ; ℂ))-operator norm with an error...
