Fractional Noether's theorem in the Riesz-Caputo sense
We prove a Noether's theorem for fractional variational problems with Riesz-Caputo derivatives. Both Lagrangian and Hamiltonian formulations are obtained.

Pohozhaev and Morawetz Identities in Elastostatics and Elastodynamics
Symmetry, Integrability and Geometry: Methods and Applications, 2011 We construct identities of Pohozhaev type, in the context of elastostatics and elastodynamics, by using the Noetherian approach. As an application, a non-existence result for forced semi-linear isotropic and anisotropic elastic systems is established.

A tropical proof of the Brill–Noether Theorem
Advances in Mathematics, 2012 We produce Brill-Noether general graphs in every genus, confirming a conjecture of Baker and giving a new proof of the Brill-Noether Theorem, due to Griffiths and Harris, over any algebraically closed field.

On Hilbert's Irreducibility Theorem [PDF]
, 1974 A method for obtaining very precise results along the lines of the Hilbert Irreducibility Theorem is described and then applied to a special case. In addition, the relationship of the irreducibility theorem to other tools of diophantine analysis is ...

A dual form of Noether's theorem with applications to continuum mechanics
, 1980 Considering simultaneously the equations of motion of the physical system and of the non-physical adjoint system, we introduce a general form of Noether's theorem by constructing a “dual Lagrangian” functional with a corresponding invariant of motion ...

An analogue of Max Noether’s theorem
Duke Mathematical Journal, 1985 It is a general hope that basic properties of complete intersections remain true for dependency loci of sections of an ample vector bundle. Along this line the author proves the following generalisation of Max Noether's theorem [see \textit{P. Deligne}, Sém. Géom. algébr. 1967- 1968, SGA 7 II, Lect. Notes Math.

The hole argument meets Noether's theorem [PDF]
The hole argument of general relativity threatens a radical and pernicious form of indeterminism. One natural response to the argument is that points belonging to different but isometric models should always be identified, or \lq{}dragged-along\rq{}, by

Noether's theorem for non-smooth extremals of variational problems with time delay
, 2014 We obtain a non-smooth extension of Noether's symmetry theorem for variational problems with delayed arguments. The result is proved to be valid in the class of Lipschitz functions, as long as the delayed Euler-Lagrange extremals are restricted to those ...

Pseudo-symmetries, Noether's theorem and the adjoint equation
, 1987 Pseudo-symmetries were introduced by Sarlet and Cantrijn (1984) for time-dependent non-conservative systems. They are reconsidered in the context of general autonomous second-order systems, relying on the new approach to such systems which was presented ...
