Unter den Voraussetzungen des Satzes von Wedderburn-Malcev wird die Existenz eines Radikalkomplementes garantiert. Deshalb stellen sich sofort zwei Fragen: Wie berechnet man ein Radikalkomplement und wie stellt man ein Element der Algebra als Summe aus einem Radikalelement und aus einem Element eines Radikalkomplementes dar? Diese Fragen beantworten wir für kommutative und für auflösbare Algebren. Die Menge der separablen Elemente spielt dabei ebenso wie eine verallgemeinerte Konstruktion der Jordan-Zerlegung eine zentrale Rolle. Wir illustrieren die Ergebnisse an verallgemeinerten Quaternionenalgebren.
About the author
Sven Bodo Wirsing was born in 1975 in Neumünster. After graduating from high school at KKS in Itzehoe (with a focus on mathematics and physics), he studied mathematics with a minor in business administration (especially logistics) at CAU university in Kiel. He did his doctorate in 2005 on group and algebra theory. During his years of study in Kiel he gained experience in the analysis of interdisciplinary processes, which are reflected in different disciplines of algebra, such as group theory, representation theory, theory of Lie and associative algebras. From this experience, he also studied and analyzed the subject matter of the present work. Since the end of his doctorate, Dr. Wirsing has been working as a senior IT consultant for logistics processes at several renowned companies where he is responsible for logistics optimization and maintenance. Since 2012 he has published several books on algebras.
