Some problems of bispectral analysis of stationary stochastic processes and uniform random fields (Q1082769)

The paper is an investigation of the statistical estimates of the bispectral density of a multivariate stochastic process and a homogeneous random field. It is proved that spectograph estimates with triangular time window are asymptotically consistent. There is an investigation of the properties of symmetry of bispectral densities. Reviewer's remark: The paper does not contain any reference to the book by \textit{T. Subba Rao} and \textit{M. M. Gabr}, An introduction to bispectral analysis and bilinear time series model. (1984; Zbl 0543.62074) and to its exhaustive bibliography concerning this field of knowledge.
