Probability on Submetric Spaces

open access: yesAnnales Mathematicae Silesianae, 2023
Abstract A submetric space is a topological space with continuous metrics, generating a metric topology weaker than the original one (e.g. a separable Hilbert space with the weak topology).

Probability theory and causation. A branching space-times analysis [PDF]

open access: yes, 2004
We provide a formally rigorous framework for integrating singular causation, as understood by Nuel Belnap's theory of causae causantes, and objective single case probabilities.

Infinite-dimensional Lie Algebras, Representations, Hermitian Duality and the Operators of Stochastic Calculus

open access: yesAxioms, 2016
We study densely defined unbounded operators acting between different Hilbert spaces. For these, we introduce a notion of symmetric (closable) pairs of operators.

BER and outage probability of DPSK subcarrier intensity modulated free space optics in fully developed speckle. [PDF]

open access: yes, 2009
In this paper a differential phase shift keying (DPSK) subcarrier intensity modulated (SIM) free space optical (FSO) link is considered in negative exponential atmospheric turbulence environment.

Predicting space climate change [PDF]

open access: yes, 2011
The recent decline in the open magnetic flux of the Sun heralds the end of the Grand Solar Maximum (GSM) that has persisted throughout the space age, during which the largest‐fluence Solar Energetic Particle (SEP) events have been rare and Galactic ...

Entropy of Fuzzy Partitions and Entropy of Fuzzy Dynamical Systems

open access: yesEntropy, 2016
In the paper we define three kinds of entropy of a fuzzy dynamical system using different entropies of fuzzy partitions. It is shown that different definitions of the entropy of fuzzy partitions lead to different notions of entropies of fuzzy dynamical ...

Common cause completability of non classical probability spaces [PDF]

open access: yesBelgrade Philosophical Annual, 2016
We prove that under some technical assumptions on a general, non-classical probability space, the probability space is extendible into a larger probability space that is common cause closed in the sense of containing a common cause of every correlation ...

Gale Duality and the Neighborliness of Random Polytopes. II

open access: yesМоделирование и анализ информационных систем, 2015
We have obtain of some distribution-independent results on the k-neighborliness of random polytopes. They confirm the well-known Gale conjecture for the general case.

Finitely additive functions in measure theory and applications [PDF]

open access: yesOpuscula Mathematica
In this paper, we consider, and make precise, a certain extension of the Radon-Nikodym derivative operator, to functions which are additive, but not necessarily sigma-additive, on a subset of a given sigma-algebra.

Basic Fuzzy Event Space and Probability Distribution of Probability Fuzzy Space

open access: yesMathematics, 2019
In this paper, the problems of basic fuzzy event space and of probability fuzzy space are studied. Firstly, the concepts of basic fuzzy event, fuzzy event and basic fuzzy event space are defined, related properties are investigated, and some results that
