In this paper, we obtain a result which implies, in particular, that for a quaternion z ∉ {−1, 1} with |z| = 1, the sum range of the series \( {\displaystyle \sum_n\frac{z^n}{n}} \) is a closed proper subfield of the division ring of quaternions

In the present paper we construct an example of a quaternion random variable such that Polya's type characterization theorem of Gaussian distributions does not hold. The matter is that in the linear form, consisting of the independent copies of quate

The main result of this paper is the formulation and proof of Polya's characterization theorem of Gaussian random variables with values in quaternion algebras. We begin with some preliminary information about quaternions and quaternion random variabl

We consider a real function which depends on the distances between a variable point and the points of a finite subset A of a linear normed space X. We show that X is an inner product space if this function attains its local minimum on a barycenter of

It is well known that for the Hilbert space H the minimum value of the functional F μ (f) = ∫ H ‖f – g‖2 dμ(g), f ∈ H, is achived at the mean of μ for any probability measure μ with strong second moment on H. We show that the validity o

To study intersections of embedded bounded closed sets in Banach space, a numerical parameter was introduced earlier; in a certain sense, this parameter describes the deviation of the shape of a set from that of a sphere. Critical values of this para
