By rewriting the differential entropy in a form of a differ-integral function’s limit, and deforming the ordinary derivative to a fractional-order one, we derive in this paper a novel generalized fractional-order differential entropy along with its related information measures. When the order of fractional differentiation <italic>α</italic> → 1, the ordinary Shannon’s differential entropy is recovered, which corresponds to the results from first-order ordinary differentiation.

The aim of this article is to introduce the concept of centrally-extended Jordan epimorphisms and proving that if <italic>R</italic> is a non-commutative prime ring (∗-ring) of characteristic not two, and <italic>G</italic> is a CE-Jordan epimorphism such that [<italic>G</italic>(<italic>x</italic>), <italic>x</italic>] ∈ <italic>Z</italic>(<italic>R</italic>) ([<italic>G</italic>(<italic>x</italic>), <italic>x</italic>∗] ∈ <italic>Z</italic>(<italic>R</italic>)) for all <italic>x</italic> ∈ <italic>R</italic>, then <italic>R</italic> is an order in a central simple algebra of dimension at most 4 over its center or there is an element <italic>λ</italic> in the extended centroid of <italic>R</italic> such that <italic>G</italic>(<italic>x</italic>) = <italic>λx</italic> (<italic>G</italic>(<italic>x</italic>) = <italic>λx</italic>∗) for all <italic>x</italic> ∈ <italic>R</italic>.

Annales Universitatis Paedagogicae Cracoviensis. Studia Mathematica

 Scope and AIM  Annales Universitatis Paedagogicae Cracoviensis Studia Mathematica (AUPC SM) publishes high quality original papers on new methods and results that hold prospect for substantial progress in mathematics. Our scope focuses on the following branches of the contemporary mathematics, namely analysis, algebra, combinatorics, geometry, number theory, and topology. However, we can also consider for publication high quality papers from other subjects that could potentially have a significant impact on the development of mathematics. We also accept well-written survey and expository papers. Short announcements on future results are not accepted.  The Editorial Board expects high standards of submissions; we look for articles that inform, stimulate, challenge, or even enlighten.  Novelty, clarity of exposition, and broad appeal lies in the priority of the journal. Appropriate figures, tables, and diagrams are strongly encouraged.  Quick and fair processing of all submissions is our priority.  All submitted papers undergo a refereeing procedure by an international board whose members represent a wide spectrum of research interests.  Publication in Annales Universitatis Paedagogicae Cracoviensis Studia Mathematica is free of charge (Diamond Open Access -- free to read and free to publish).  Volumes I-VII appeared as Annales Academiae Paedagogicae Cracoviensis Studia Mathematica.  Archiving  Sciendo archives the contents of this journal in Portico - digital long-term preservation service of scholarly books, journals and collections.  Plagiarism Policy  The editorial board is participating in a growing community of Similarity Check System's users in order to ensure that the content published is original and trustworthy. Similarity Check is a medium that allows for comprehensive manuscripts screening, aimed to eliminate plagiarism and provide a high standard and quality peer-review process.  Target Group- researchers in all branches of pure mathematics
