Yang-Mills as massive Chern-Simons theory: a third way to three-dimensional gauge theories.

The Yang-Mills (YM) equation in three spacetime dimensions (3D) can be modified to include a novel parity-preserving interaction term, with an inverse mass parameter, in addition to a possible topological mass term. The novelty is that the modified YM equation is not the Euler-Lagrange equation of any gauge-invariant local action for the YM gauge potential alone. Instead, consistency is achieve...

A Third Way for Health Policy?

Economics has hit the mainstream in the last decade with popular books like Freakonomics and The Undercover Economist reaching the masses. These authors have used their toolkits far beyond the narrow scope of money and finance and answered questions pertaining to anything from social policy to demographics to crime. Their appeal has largely been their ability to explain that small underlying fo...

Hippocampal Contributions to Control: The Third Way

Recent experimental studies have focused on the specialization of different neural structures for different types of instrumental behavior. Recent theoretical work has provided normative accounts for why there should be more than one control system, and how the output of different controllers can be integrated. Two particlar controllers have been identified, one associated with a forward model ...

The Third Way to 3D Gravity

Consistency of Einstein’s gravitational field equation Gμν ∝ Tμν imposes a “conservation condition” on the T -tensor that is satisfied by (i) matter stress tensors, as a consequence of the matter equations of motion, and (ii) identically by certain other tensors, such as the metric tensor. However, there is a third way, overlooked until now because it implies a “nongeometrical” action: one not ...
