Variational Problems with Partial Fractional Derivative: Optimal Conditions and Noether’s Theorem
In this paper, the necessary and sufficient conditions of optimality for variational problems with Caputo partial fractional derivative are established. Fractional Euler-Lagrange equations are obtained.

Analogues to Lie Method and Noether’s Theorem in Fractal Calculus
In this manuscript, we study symmetries of fractal differential equations. We show that using symmetry properties, one of the solutions can map to another solution.

The equivalence principle is NOT a Noether symmetry
The connection between the equivalence principle and Noether’s theorem was discussed in Capozziello and Ferrara (Int J Geom Methods Mod Phys 21:2440014, 2024).

Moving energies hide within Noether’s first theorem [PDF]
We show that the moving energies of some well-known nonholonomic systems are hidden among the first integrals that can be obtained by applying Noether’s first Theorem to a suitable ...

The Unitary Master Ward Identity: Time Slice Axiom, Noether’s Theorem and Anomalies [PDF]
The C*-algebraic formulation of generic interacting quantum field theories, recently presented by Detlev Buchholz and one of the authors (KF), is enriched by a unitary version of the Master Ward Identity, which was postulated some time ago by Franz Marc ...

Noether’s theorem for Herglotz type variational problems utilizing complex fractional derivatives [PDF]
This is a review article which elaborates the results presented in [1], where the variational principle of Herglotz type with a Lagrangian that depends on fractional derivatives of both real and complex orders is formulated and the invariance of this ...

Euler-Lagrange equations and Noether’s theorem of multi-scale mechano-electrophysiological coupling model of neuron membrane dynamics [PDF]
Noether’s theorem is applied into a multi-scale mechno-electrophysiological coupling model of neuron membrane dynamics. The Euler-Lagrange equations in generalized coordinates of this model are deduced by the nonconservative Hamilton principle.
