Radziecki matematyk Andriej Nikołajewicz Kołmogorow (1903‒1987), autor ponad pół tysiąca prac naukowych, był jednym z najwybitniejszych matematyków XX wieku i w pewnym momencie być może nawet największym. W 1960 roku, Kołmogorow rozpocz

A potential theory approach to an algorithm of conceptual space partitioning This paper proposes a new classification algorithm for the partitioning of a conceptual space. All the algorithms which have been used until now have mostly been based on t

We consider the Green functions for second-order left-invariant differential operators on homogeneous manifolds of negative curvature, being a semi-direct product of a nilpotent Lie group $N$ and $A=mathbb{R}^+$. We obtain estimates for mixed derivat

This paper deals with Gärdenfors’ theory of conceptual spaces. Let $${\mathcal {S}}$$ S be a conceptual space consisting of 2-type fuzzy sets equipped with several kinds of metrics. Let a finite set of prototypes $$\tilde{P}_1,\ldots ,\tilde{P}_n\

Let K be a fixed proper convex cone contained in a separable Banach space E. Our main result in this note is a construction of a fuzzy process taking values in K-positive fuzzy sets, i.e. in a cone F c c o n v K ( E ) $ \mathcal F_{\mathrm{cconv}}^{K

We prove an analogue of the Donsker theorem under the Lindeberg condition in a fuzzy setting. Specifically, we consider a certain triangular system of d-dimensional fuzzy random variables { X n , i ∗ } , $\begin{array}{} \{X_{n,i}^*\}, \end{array}$
