Translations as inner derivations and associativity anomalies in open string field theory
Physics Letters B, 1987 Abstract We show that spacetime translations are inner derivations of Witten's star algebra for open bosonic string field theory. The connection between inner derivations and gauge transformations is discussed. This result is in conflict with the naive expectation that the string midpoint is fixed in the star algebra.

The consistency of topological expansions in field theory: “BRST anomalies” in strings and Yang-Mills [PDF]
Nuclear Physics B, 1994 Many field theories of physical interest have configuration spaces consisting of disconnected components. Quantum mechanical amplitudes are then expressed as sums over these components. We use the Faddeev-Popov approach to write the terms in this topological expansion as moduli space integrals. A cut-off is needed when these integrals diverge.

Closed Strings Tachyons and Non-Commutative Instabilities [PDF]
, 2003 We observe a relation between closed strings tachyons and one-loop instabilities in non-supersymmetric non-commutative gauge theories. In particular we analyze the spectra of type IIB string theory on C^3/Z_N orbifold singularities and the non ...

Anomalies, Anomalous U(1)'s and generalized Chern-Simons terms [PDF]
, 2006 A detailed analysis of anomalous U(1)'s and their effective couplings is performed both in field theory and string theory. It is motivated by the possible relevance of such couplings in particle physics, as well as a potential signal distinguishing ...

Trace anomalies and the string-inspired definition of quantum-mechanical path integrals in curved space [PDF]
, 1998 We consider quantum-mechanical path integrals for non-linear sigma models on a circle defined by the string-inspired method of Strassler, where one considers periodic quantum fluctuations about a center-of-mass coordinate.

Relating ’t Hooft anomalies of 4d pure Yang-Mills and 2d ℂℙ N− 1 model
Journal of High Energy Physics, 2018 It has recently been shown that a center-twisted compactification of the four-dimensional pure SU(N) Yang-Mills theory on a three-torus gives rise to the twodimensional ℂℙ N− 1-model on a circle with a flavor-twisted boundary condition.

Relativistic hydrodynamics with the parity anomaly
Journal of High Energy Physics, 2022 We consider the hydrodynamic regime of a 2+1 dimensions QFT with the parity anomaly. Beyond the known constraints from positivity of entropy production, we show that the anomaly inflow mechanism, from a corresponding bulk SPT phase, together with ...

The Anomaly Structure of Regularized Supergravity [PDF]
, 2014 On-shell Pauli-Villars regularization of the one-loop divergences of supergravity theories is used to study the anomaly structure of supergravity and the cancellation of field theory anomalies under a $U(1)$ gauge transformation and under the T-duality ...

Non-invertible Gauss law and axions
Journal of High Energy Physics, 2023 In axion-Maxwell theory at the minimal axion-photon coupling, we find non-invertible 0- and 1-form global symmetries arising from the naive shift and center symmetries.

Marginal and Relevant Deformations of N=4 Field Theories and Non-Commutative Moduli Spaces of Vacua [PDF]
, 2000 We study marginal and relevant supersymmetric deformations of the N=4 super-Yang-Mills theory in four dimensions. Our primary innovation is the interpretation of the moduli spaces of vacua of these theories as non-commutative spaces.
