Four papers are in progress : on the block eigenvalue solver in the TT-format, on the dynamical low-rank approximation, on the tensor structure of the wavelet tensor train matrix and on the fast solution of the Stokes problem in tensor format. Hope to finish them soon.
Also, I put some time to get an implementation of the TT-Toolbox in Python. The preliminary version (ttpy 0.1) is available on the github. Please take a look on it, if you are interested.
