Discrete U-duality Groups

Generators for the discrete U-duality groups of toroidally compactified M-theory in d ≥ 4 are presented and used to determine the d = 3 U-duality group. This contribution summarizes the results of [1].

’t HOOFT ANOMALY MATCHING FOR DISCRETE SYMMETRIES

We show how to extend the ’t Hooft anomaly matching conditions to discrete symmetries. We check these discrete anomaly matching conditions on several proposed low-energy spectra of certain strongly interacting gauge theories. The excluded examples include the proposed chirally symmetric vacuum of pure N = 1 supersymmetric Yang-Mills theories, certain nonsupersymmetric confining theories and som...

Anomaly Reconciliation in Electronic Discussion Groups

According to public goods theory, there should be a deficiency of knowledge shared in electronic discussion groups (EDG) because self-interested individuals would be motivated to receive others’ knowledge but not to share their own. A number of motivators (such as generalized reciprocity, altruism, and normative obligations) have been proposed to explain why people actually do share their knowl...
