Annotatsiya

In this paper a new (symmetric) product for matrices, entries of which are located by pair of multi-indices, and norms of such matrices are introduced. They are used to represent multivariate power series as series in one (vector) variable and to introduce a radius of absolute convergence. For the radius of absolute convergence a formula, similar to ordinary Cauchy-Hadamard formula in one variable case, is given. Some open problems related to the radius of absolute convergence are set.
