Fractional Time-Scales Noether’s Theorem for Non-Standard Birkhoffian System

Fractal and Fractional
In this work, Noether symmetries and conserved quantities of a non-standard Birkhoffian system based on the Caputo Δ Pfaff–Birkhoff principle on time scales are studied.

Covariant Canonical Method for Yang-Mills Theory Expressed as a Constrained BF-Like Theory

Advances in Mathematical Physics, 2012
The covariant canonical analysis for Yang-Mills theory expressed as a BF-like action is performed. We study a BF-like action, that in spite of being the coupling of two topological terms, yield, on shell to Yang-Mills action.

Noether’s theorem and Ward-Takahashi identities from homotopy algebras

Journal of High Energy Physics
We derive the new identity in homotopy algebras which directly corresponds to the Schwinger-Dyson equations in quantum field theory. As an application, we derive the Ward-Takahashi identities.

ABJ anomaly as a U(1) symmetry and Noether’s theorem

SciPost Physics
The Adler-Bell-Jackiw anomaly determines the violation of chiral symmetry when massless fermions are coupled to an abelian gauge field. In its seminal paper, Adler noticed that a modified chiral $U(1)$ symmetry could still be defined, at the expense of ...

A Century Of Noether'S Theorem

, 2018
Fermilab Colloquium, August 15, 2018. Abstract: In the summer of 1918, Emmy Noether published the theorem that now bears her name, establishing a profound connection between symmetries and conservation laws. The influence of this insight is pervasive in physics; it underlies all of our theories of the fundamental interactions and gives meaning to ...

Connections Between Symmetries and Conservation Laws

Symmetry, Integrability and Geometry: Methods and Applications, 2005
This paper presents recent work on connections between symmetries and conservation laws. After reviewing Noether's theorem and its limitations, we present the Direct Construction Method to show how to find directly the conservation laws for any given ...
