摘要：
In this paper QTT-approximations to elliptic solution operators with constant coefficients in d-dimensional cube are constructed. The epsilon-accurate representations of the Frobenius norm can be computed with the complexity O(d log(q) epsilon(-1)), where d >= 2 is the spatial dimension, and q >= 2 is some fixed constant.
