Paperback. Condición: New. Let V be a vertex operator algebra with a category C of (generalized) modules that has vertex tensor category structure, and thus braided tensor category structure, and let A be a vertex operator (super)algebra extension of V . We employ tensor categories to study untwisted (also called local) A-modules in C, using results of Huang-Kirillov-Lepowsky that show that A is a (super)algebra object in C and that generalized A-modules in C correspond exactly to local modules for the corresponding (super)algebra object. Both categories, of local modules for a C-algebra and (under suitable conditions) of generalized A-modules, have natural braided monoidal category structure, given in the first case by Pareigis and Kirillov-Ostrik and in the second case by Huang-Lepowsky-Zhang.Our main result is that the Huang-Kirillov-Lepowsky isomorphism of categories between local (super)algebra modules and extended vertex operator (super)algebra modules is also an isomorphism of braided monoidal (super)categories. Using this result, we show that induction from a suitable subcategory of V -modules to Amodules is a vertex tensor functor. Two applications are given: First, we derive Verlinde formulae for regular vertex operator superalgebras and regular 1 2Z-graded vertex operator algebras by realizing them as (super)algebra objects in the vertex tensor categories of their even and Z-graded components, respectively.…

Taschenbuch. Condición: Neu. Druck auf Anfrage Neuware - Printed after ordering - 150 years after the first description of the clinical picture of 'white blood' and the introduction of the term 'leukemia' by R. Virchow it appears, that the leukemias, and the acute leukemias in particular, serve as an impressive example for the major improvements that have been achieved in the treatment but also in the understand ing of the biology of malignant dis orders. The international symposia 'Acute Leukemia' which are held at Münster since 1986 have developed into an interna tional forum to review the current progress and the future perspectives of leukemia research and therapy at a high scientific and clinicallevel. Since the possibility for active participation in these symposia is somewhat restricted we are glad to have the opportunity to extend the information that was presented at the symposium 'Acute Leukemias V - Experimental Approaches and Management of Refractory Disease' which was held from February 27 to March 2, 1994 to a broader audience of basic scientists and clinicians. This meeting was especiaIly designed to discuss experimen tal approaches and the management of refractory disease which allows to evaluate new experimental therapies on the basis of preclinical studies.…

Paperback. Condición: New. This volume contains the proceedings of the thematic program on ""Quantum symmetries: Tensor categories, topological quantum field theories, and vertex algebras"" held from October 10 -November 4, 2022, at the Centre de Recherches Mathematiques, Montreal, Quebec, Canada. Quantum symmetries is a rapidly expanding area in which tensor categories are applied to mathematical physics, in particular, to conformal and topological quantum field theories. These fields, in turn, connect to a huge variety of modern mathematics, including representation theory, vertex operator algebras, Hopf algebras, link and knot invariants, geometry, subfactors, combinatorics, and so much more. The thematic program on quantum symmetries featured advanced lecture courses and research seminars by international leaders of their respective fields. This proceedings volume is centered on the active research of the area, but also includes an in-depth survey of one of the main topics, $W$-algebras. …
