It is well known that there are close relations between classes of singularities and representation theory via the McKay correspondence and between representation theory and vector bundles on projective spaces via the Bernstein-Gelfand-Gelfand construction. These relations however cannot be considered to be either completely understood or fully exploited. These proceedings document recent developments in the area. The questions and methods of representation theory have applications to singularities and to vector bundles. Representation theory itself, which had primarily developed its methods for Artinian algebras, starts to investigate algebras of higher dimension partly because of these applications. Future research in representation theory may be spurred by the classification of singularities and the highly developed theory of moduli for vector bundles. The volume contains 3 survey articles on the 3 main topics mentioned, stressing their interrelationships, as well as original research papers.

In unserer technisierten Welt stoßen wir überall auf Mathematik. Mathematik ist eine Basiswissenschaft und der Schlüssel für bahnbrechende Innovationen. Sie macht viele Produkte und Dienstleistungen überhaupt erst möglich und ist damit ein wichtiger Produktions- und Wettbewerbsfaktor.Im vorliegenden Buch berichten 19 große internationale Unternehmen sowie die Bundesagentur für Arbeit wie unverzichtbar Mathematik für ihren Erfolg heute geworden ist. Ein spannender und lehrreicher Einblick in die Mathematik, der mit oft zitierten und negativen Vorurteilen gründlich aufräumt.

Singularity theory is a young, rapidly-growing topic with connections to algebraic geometry, complex analysis, commutative algebra, representations theory, Lie groups theory and topology, and many applications in the natural and technical sciences.

This substantially enlarged second edition aims to lead a further stage in the computational revolution in commutative algebra. This is the first handbook/tutorial to extensively deal with SINGULAR.

Singular algebraic curves have been in the focus of study in algebraic geometry from the very beginning, and till now remain a subject of an active research related to many modern developments in algebraic geometry, symplectic geometry, and tropical geometry.
