Full text linkErdélyi László Gyula OSB szakmai életútja különös tekintettel egyetemi pályájára
Full text linkLászló Gyula Erdélyi (1868-1947) was one of the most important researchers and university professors of the end of the 19th and during the first half of the 20th century, especially between 1900 and 1930 in Hungary. His research interest focused on the medieval Hungarian history. From 1892 to 1938, Erdélyi held leading positions in several Hungarian institutions, colleges and universities: he was college teacher in Pannonhalma, then worked as professor at the universities in Cluj and Szeged, at the latter he was also head of department, dean and rector. No comprehensive career trajectory of Erdélyi has yet been researched and this present dissertation is an essential contribution in this regard and more generally, to the history of Hungarian science. Moreover, the dissertation’s results are important not only for the Catholic church history but also for public memory and social history. László Erdélyi's most productive field of activity was his university work and, as a result, this dissertation focuses on the systematic development of his research and teaching activities, which were insofar absent from the Hungarian cultural history materials
Muster und Beschränkungen der Wortbildung mit Negationsbedeutung im Deutschen
Full text linkDie Arbeit behandelt Wortbildung mit Negationsbedeutung im Deutschen mit folgenden Wortbildungseinheiten: 'a'- (z. B. 'asozial'), 'in'- (z. B. 'inaktiv'), 'nicht'- (z. B. 'nichtdemokratisch'), 'non'- (z. B. 'nonchalant'), 'un'- (z. B. 'unzufrieden'). Im Rahmen der Arbeit wird das Ziel verfolgt, Wortbildung mit den behandelten Einheiten im gesprochenen Standarddeutsch systematisch und einheitlich zu beschreiben, um sie miteinander vergleichen zu können und dadurch die Frage beantworten zu können, ob und welche formalen, kategorialen und semantischen Unterschiede es zwischen ihnen gibt. Als zentrale Fragen werden die mit den Wortbildungseinheiten verbundenen Wortbildungsbedeutungen, die Beschränkungen der Wortbildungsmuster, die Akzentuierung der Wortbildungsprodukte und der Status der Wortbildungseinheit 'nicht'- behandelt
Solution sets and centralizers
Full text linkWe study solution sets of systems of equations over arbitrary finite algebras. The essence of our investigation is characterizing the solution sets with a certain type of closure condition. A well-known theorem in linear algebra states that a set of tuples is a solution set of some system of linear equations if and only if it is closed under affine combinations. Following the example of systems of linear equations, for any algebra, we can find a set of operations such that the solution sets are always closed under these operations. If this closure is sufficient as well (that is, every closed set is also a solution set of some system of equations), then we will say that the investigated algebra has property (SDC). This thesis studies algebras with property (SDC) and properties that are equivalent to property (SDC). In the first chapter we introduce the basic definitions. In the second chapter we show that the solution set of a system of equations over any finite algebra is closed under the centralizer of the algebra, and introduce property (SDC). Moreover, we prove that property (SDC) is equivalent to quantifier elimination of certain type of primitive positive formulas. In the third chapter we prove that every two-element algebra has property (SDC). In the fourth chapter we investigate centralizers of finite semilattices, distributive lattices and lattices. In the fifth chapter we give all finite semilattices and lattices having property (SDC). In the sixth chapter we prove that property (SDC) is equivalent to polymorphism-homogeneity, and also to injectivity in a well-chosen class of algebras. Then we describe algebras with property (SDC) in some important classes of algebras
