Abstract

The main contribution of this paper is the homogenization of the linear parabolic equation t u ε ( x , t ) - · ( a ( x / ε q 1 , . . . , x / ε q n , t / ε r 1 , . . . , t / ε r m ) u ε ( x , t ) ) = f ( x , t ) exhibiting an arbitrary finite number of both spatial and temporal scales. We briefly recall some fundamentals of multiscale convergence and provide a characterization of multiscale limits for gradients, in an evolution setting adapted to a quite general class of well-separated scales, which we name by jointly well-separated scales (see appendix for the proof). We proceed with a weaker version of this concept called very weak multiscale convergence. We prove a compactness result with respect to this latter type for jointly well-separated scales. This is a key result for performing the homogenization of parabolic problems combining rapid spatial and temporal oscillations such as the problem above. Applying this compactness result together with a characterization of multiscale limits of sequences of gradients we carry out the homogenization procedure, where we together with the homogenized problem obtain n local problems, that is, one for each spatial microscale. To illustrate the use of the obtained result, we apply it to a case with three spatial and three temporal scales with q 1 = 1 , q 2 = 2 , and 0 < r 1 < r 2 .
