Complex-Valued Functions with Nondegenerate Groups of Regular Points

Complex-valued functions with nondegenerate groups of regular points are studied in the paper. A class of functions , which takes value on the complex plain and for which the limit exists, and is nonzero and finite for some from subset of positive real numbers is considered. It was received that this subset is multiplicative group, and it is called the group of regular points. Functions with nondegenerate groups of regular points generalize the class of RV functions. The corresponding limit functions are defined for complex-valued functions with nondegenerate groups of regular points.

Some asymptotic properties of dispersion matrices of the estimation error for kalman-bjusy filters

This paper deals with asymptotic properties of some Kalman-Bjusy filters. We also consider the conditions of convergence of dispersion matrices sequence of the estimation error and the properties of the limit matrix.
