On certain functional equation in prime rings
Maja Fošner, Benjamin Marcen, Joso Vukman, 2022, izvirni znanstveni članek

Opis: The purpose of this paper is to prove the following result. Let R be prime ring of characteristic different from two and three, and let F:R→R be an additive mapping satisfying the relation F(x3)=F(x2)x−xF(x)x+xF(x2) for all x∈R. In this case, F is of the form 4F(x)=D(x)+qx+xq for all x∈R, where D:R→R is a derivation, and q is some fixed element from the symmetric Martindale ring of quotients of R.

Računalništvo in informatika v logistiki
Roman Gumzej, 2024

Opis: Učbenik je namenjen predvsem študentom prvih letnikov visokošolskega strokovnega in univerzitetnega študijskega programa Fakultete za logistiko. Je osnovna literatura učnih predmetov Osnove računalništva v logistiki na visokošolskem strokovnem in Računalništvo v logistiki na univerzitetnem študijskem programu. V okviru teh predmetov zasnujemo logistične informacijske sisteme. Predstavimo njihov pomen, vlogo in naloge ter komponente: računalniška podatkovna, strojna, mrežna, programska in organizacijska oprema. Pri praktičnem delu se posvetimo predvsem računalniško podprtemu inženiringu logističnih informacijskih sistemov na univerzitetnem ter poslovni analitiki in podpori odločanju na visokošolskem strokovnem programu. Vsebino sklenemo z metodami in mehanizmi za zagotavljanje varnosti računalniško podprtih logističnih informacijskih sistemov. Učbenik predstavlja osnovo za naknadno obravnavo specializiranih vsebin pri predmetih Poslovni informacijski sistemi v logistiki, Informacijska podpora logističnim sistemom in procesom ter Integracije logističnih informacijskih sistemov.

Opis: The scientific monograph titled Logistics and Management – selected topics is the result of a bilateral project, lasting from 2013 to 2015 and titled “Preparation of a joint scientific monograph in the field of logistics and management issued at the Faculty of Logistics in Celje and the Maritime Faculty of Kotor”. The project was managed by Professor Maja Fošner, PhD, from the Faculty of Logistics at the University of Maribor, and Professor Veselin Draskovic, PdD, from the Maritime Faculty of Kotor, Montenegro. The main goal of the monograph is to give a comprehensive account of selected areas from the field of logistics and challenges in the development of logistics, such as risk management and supply chains, transport cost, competences in logistics, urban logistics, green logistics, seaport cooperation, logistics network optimisation, logistics in tourism, logistics in performance management, systemic logistics providers and solutions to problems of transportation task. Wishing to offer a comprehensive presentation of various areas in the field of logistics, the authors of the monograph contributions, who participated on the project (Maja Fošner, Bojan Rosi, Borut Jereb, Marjan Sternad, Veselin Draskovic (ed.), Mimo Draskovic, Sanja Bauk, Senka Sekulac-Ivosevic), invited to cooperation also other researchers from the Faculty of Logistics and the Maritime Faculty of Kotor (Irena Gorenak, Matjaž Knez, Matevž Obrecht, Sonja Mlaker Kač, Tina Cvahte, Darja Topolsek, Drago Pupavac, Zeljko Ivanovic, Oleksandr Dorokhov, and Ludmila Malyaretz) who enriched the present monograph with their contributions.

Logistics, supply chain, sustainability and global challenges
2007, revija

Opis: The journal of Logistics & sustainable transport publishes informative and analytical international scientific and professional articles in the field of logistics and sustainable transport. Subject areas include logistics and related transport infrastructure, technological, operational, economic, and other environmental, social and institutional issues. This scope makes the journal inter- and multidisciplinary and in particular, a convenient source of information for logistics and transport researchers, planners, practitioners and policy makers at different - local, national and international levels, and across disciplines such as technology design, planning, implementation, management, policy-making, social, economic and environmental regulation.

An Engel condition with an additive mapping in semiprime rings
Maja Fošner, Nadeem Ur Rehman, Joso Vukman, 2014, izvirni znanstveni članek

Opis: The main purpose of this paper is to prove the following result: Let n > 1 be a fixed integer, let R be a n!-torsion free semiprime ring, and let f : R -> R be an additive mapping satisfying the relation [f (x), x]n = [[. . . [[f (x), x], x], . . .], x] = 0 for all x = R. In this case [f (x), x] = 0 is fulfilled for all x = R. Since any semisimple Banach algebra (for example, C algebra) is semiprime, this purely algebraic result might be of some interest from functional analysis point of view.

Jordan superderivations. II
Maja Fošner, 2004, izvirni znanstveni članek

Opis: In a recent paper we have extended the classical Herstein's theorem on Jordan derivations on prime rings to Jordan superderivations on prime associative superalgebras. In the present paper we extend this result to semiprime associative superalgebras.

An identity with derivations on rings and Banach algebras
Ajda Fošner, Maja Fošner, Joso Vukman, 2008, izvirni znanstveni članek

Opis: The main purpose of this paper is to study the following: Let m, n, and $k_{i}, i = 1, 2, ..., n$ be positive integers and let $R$ be a $2m(m+ k_{1} + k_{2} + ... + k_{n} -1)!$-torsion free semiprime ring. Suppose that there exist derivations $D_{i} : R \to R, i = 1, 2, ..., n + 1$ , such that $D_{1}(x^{m})x^{k_{1}+...+k_{n}}+x^{k_{1}} D_{2}(x^{m})x^{k_{2}+...+k_{n}}+...+x^{k_{1}+...+k_{n}}D_{n+1}(x^{m})=0$ holds for all $x \in R$. Then we prove that $D_{1}+D_{2}+...+D_{n+1}=0$ and that the derivation $k_{1}D_{2}+(k_{1}+k_{2})D_{3}+...+(k_{1}+k_{2}+...+k{n})D_{n+1}$ maps $R$ into its center. We also obtain a range inclusion result of continuous derivations on Banach algebras.

Aditivne preslikave z dodatnimi lastnostmi na (pol)prakolobarjih in standardnih operatorskih algebrah
Benjamin Marcen, 2016, doktorska disertacija

Opis: V doktorski disertaciji si bomo v uvodu ogledali nekaj osnovnih pojmov, definicij ter pomembnejših rezultatov s področja algebre. Obravnavali bomo funkcionalne enačbe, ki so v zvezi z odvajanji, centralizatorji ter sorodnimi preslikavami na prakolobarjih, polprakolobarjih in standardnih operatorskih algebrah. Na tem področju že vrsto let delujejo tudi slovenski matematiki, ki so s svojimi rezultati pomembno vplivali na razvoj tega področja. Že v osemdesetih letih sta bila močno dejavna na tem področju J. Vukman, M. Brešar, sledili pa so B. Zalar, B. Hvala, v novejšem času pa M. Fošner, I. Kosi-Ulbl, D. Benkovič, D. Eremita, A. Fošner, N. Peršin ter N. Širovnik. Osnovno sredstvo pri reševanju funkcionalnih enačb, ki bodo predstavljene v disertaciji, je teorija funkcijskih identitet, ki jo je leta 2000 v cite{87} predstavil M. Brešar. Leta 2007 pa so jo M. Brešar, M. A. Chebotar in W. S. Martindale III tudi podrobneje predstavili v knjigi cite{MB4}. Teorija funkcijskih identitiet bo v disertaciji predstavljena skupaj s polinomskimi identitietami ter d-prostimi množicami.
Ključne besede: Aditivna preslikava, linearen operator, odvajanje, jordansko odvajanje, jordansko trojno odvajanje, centralizator, funkcionalna enačba, standardna operatorska algebra, prakolobar, polprakolobar, Banachov prostor, involucija.
