Computational Invariant Theory

By: Harm Derksen,Gregor Kemper

This book is about the computational aspects of invariant theory. Of central interest is the question how the invariant ring of a given group action can be calculated. Algorithms for this purpose form the main pillars around which the book is built. There are two introductory chapters, one on Gröbner basis methods and one on the basic concepts of invariant theory, which prepare the ground for the algorithms. Then algorithms for computing invariants of finite and reductive groups are discussed. Particular emphasis lies on interrelations between structural properties of invariant rings and computational methods. Finally, the book contains a chapter on applications of invariant theory, covering fields as disparate as graph theory, coding theory, dynamical systems, and computer vision. The book is intended for postgraduate students as well as researchers in geometry, computer algebra, and, of course, invariant theory. The text is enriched with numerous explicit examples which illustrate the theory and should be of more than passing interest. More than ten years after the first publication of the book, the second edition now provides a major update and covers many recent developments in the field. Among the roughly 100 added pages there are two appendices, authored by Vladimi r Popov, and an addendum by Norbert A'Campo and Vladimir Popov.

A Course in Commutative Algebra

By: Gregor Kemper

This textbook offers a thorough, modern introduction into commutative algebra. It is intented mainly to serve as a guide for a course of one or two semesters, or for self-study. The carefully selected subject matter concentrates on the concepts and results at the center of the field. The book maintains a constant view on the natural geometric context, enabling the reader to gain a deeper understanding of the material. Although it emphasizes theory, three chapters are devoted to computational aspects. Many illustrative examples and exercises enrich the text.

FinTech and Data Privacy in Germany

An Empirical Analysis with Policy Recommendations

By: Gregor Dorfleitner,Lars Hornuf

This book examines the FinTech revolution from a data privacy perspective. It analyzes key players on the FinTech market and the developments in various market segments. Particular attention is paid to an empirical analysis of the privacy statements of 505 German FinTech firms and how they were adapted after the General Data Protection Regulation (GDPR) entered into effect in May 2018. The analysis also includes 38 expert interviews with relevant stakeholders from supervisory and regulatory authorities, the financial and FinTech industry, leading consulting firms and consumer protection agencies. By adopting this approach, the book identifies key regulatory needs, offers a valuable asset for practitioners and academics alike, and shares intriguing insights for lawyers, economists and everyone interested in FinTech and data privacy.

Robert Rauschenberg's »Erased de Kooning Drawing« (1953)

Modernism, Literalism, Postmodernism

By: Gregor Stemmrich

Erased de Kooning Drawing ist ein Kunstwerk, das auf radikale Weise die Definition von Kunst und das Verständnis von Autorschaft herausfordert. Drei amerikanische Künstler waren 1953 an seiner Erschaffung beteiligt: Robert Rauschenberg radierte eine Zeichnung Willem de Koonings aus, der mit einem gewissen Widerwillen sein Einverständnis gegeben hatte. Jasper Johns versah es anlässlich seiner ersten Präsentation mit einem Label, das maßgeblich zu seiner Wahrnehmung als eigenständigem Werk beitrug. Das zu etwas Neuem transformierte Blatt wurde in den 1950er-Jahren als Neo-Dada aufgefasst, in den 1960ern als Beginn der Konzeptkunst und in den 1980er-Jahren als Aufbruch in die Postmoderne. Zahlreiche Künstler*innen bezogen sich auf das Werk und Rauschenberg selbst griff es immer wieder auf. Es erwies sich als Testfall für Bestimmungen von Modernismus, Literalismus und Postmodernismus. Gregor Stemmrichs kenntnisreiche kunsttheoretische Betrachtung arbeitet die anhaltende Relevanz des Werks für die Theorie des Bildes, des Index, der Spur, des Allegorischen und der Frage nach Appropriation heraus.
