Abstract
The following Cauchy problem for parabolic equations is considered in the half-space \( \overline{D}={\mathrm{\mathbb{R}}}^N\times \left[0,\infty \right) \), N ≥ 3:
It is proved that for any bounded and continuous in ℝN initial function u0(x), the solution of the above Cauchy problem stabilizes to zero uniformly with respect to x from any compact set K in ℝN either exponentially or as a power (depending on the estimate for the coefficient c(x, t) of the equation).
