A Poster about the Old History of Fractional Calculus

Tenreiro Machado, J., Kiryakova, Virginia, Mainardi, Francesco (2010)

Fractional Calculus and Applied Analysis

MSC 2010: 26A33, 05C72, 33E12, 34A08, 34K37, 35R11, 60G22The fractional calculus (FC) is an area of intensive research and development. In a previous paper and poster we tried to exhibit its recent state, surveying the period of 1966-2010. The poster accompanying the present note illustrates the major contributions during the period 1695-1970, the "old history" of FC.

A probabilistic ergodic decomposition result

Albert Raugi (2009)

Annales de l'I.H.P. Probabilités et statistiques

Let ( X , 𝔛 , μ ) be a standard probability space. We say that a sub-σ-algebra 𝔅 of 𝔛 decomposes μ in an ergodic way if any regular conditional probability 𝔅 P with respect to 𝔅 andμ satisfies, for μ-almost every x∈X, B 𝔅 , 𝔅 P ( x , B ) { 0 , 1 } . In this case the equality μ ( · ) = X 𝔅 P ( x , · ) μ ( d x ) , gives us an integral decomposition in “ 𝔅 -ergodic” components. For any sub-σ-algebra 𝔅 of 𝔛 , we denote by 𝔅 ¯ the smallest sub-σ-algebra of 𝔛 containing 𝔅 and the collection of all setsAin 𝔛 satisfyingμ(A)=0. We say that 𝔅 isμ-complete if 𝔅 = 𝔅 ¯ . Let { 𝔅 i i I } be a non-empty family...

A probability density function estimation using F-transform

Michal Holčapek, Tomaš Tichý (2010)

Kybernetika

The aim of this paper is to propose a new approach to probability density function (PDF) estimation which is based on the fuzzy transform (F-transform) introduced by Perfilieva in [10]. Firstly, a smoothing filter based on the combination of the discrete direct and continuous inverse F-transform is introduced and some of the basic properties are investigated. Next, an alternative approach to PDF estimation based on the proposed smoothing filter is established and compared with the most used method...
