Recenzii

“The present book Tensor spaces and numerical tensorcalculus by Wolfgang Hackbusch to a large extent fills the gap between theoryon finite-dimensional tensor spaces and tensor computations. It also gives acomprehensive overview of numerical tensor computations. … the book is mostuseful as a (very rich) source book for researchers in the area. It might also beused as a textbook for a Ph.D. course … .” (Lars Eldén, Mathematical Reviews,October, 2015)

Textul de pe ultima copertă

Special numerical techniques are already needed to deal with nxn matrices for large n. Tensor data are of size nxnx...xn=n^d, where n^d exceeds the computer memory by far. They appear for problems of high spatial dimensions. Since standard methods fail,
a particular tensor calculus is needed to treat such problems.
The monograph describes the methods how tensors can be practically treated and how numerical operations can be performed. Applications are problems from quantum chemistry, approximation of multivariate functions, solution of pde, e.g., with stochastic coefficients, etc.
