Modular Localization and Nonperturbative Local Quantum Physics

The main content of this treatise is a new concept in nonperturbative non-Lagrangian QFT which explains and extends the ad hoc constructions in low-dimensional models and incorporates them together with the higher dimensional theories into a new construction method. Thermal and entropical properties, which were hitherto restricted to situations with classical horizons (Killing vectors), are now generic (nonperturbative) aspects of "modular localization". The underlying more algebraic (and less geometric) mode of thinking also gives rise to interesting questions in renormalizable deformatioms of higher spin fields, in particular gauge theories
