SUMMARY:Seminar: Dan Freed (University of Texas): "What is an anomaly?"
DESCRIPTION:<strong><drupal-media data-entity-type="media" data-entity-uuid="5846f7e1-e34c-4378-a456-2c65ce0f7ecc" alt="Dan Freed" data-view-mode="hwp_small"></drupal-media><br>Speaker: </strong>Dan Freed (University of Texas)<br><strong>Title: </strong>What is an anomaly?<br><strong>Abstract: </strong>Anomalies in quantum field theory have been the subject of attention for decades. In this talk I will dispel some myths: anomalies are tied to symmetry, anomalies are tied to fermionic fields, etc. Then I will explain how anomalies--expressed as invertible field theories--are the manifestation of the projectivity of quantum field theory. My point of view is summarized by a slogan: Quantum theory is projective. Quantization is linear.
