Some Notable Papers By S. Deser

* Observations regarding the nature of how the mass of fundamental particles arises from their gravitational and non-gravitational self-interactions.

* How special relativity determines the sign of electromagnetism and gravity.

* Analysis of the gravitational self-interaction (1970); clarified and expanded upon in 2009.  (Criticism of this result and a similar one by Feynman in 1995 that shows an out of the box thinking alternative analysis can be found here).  And, some related non-obvious observations about the properties of stress energy tensors.  Also graviton-graviton scattering drawing on SUGRA (i.e. the gravitational extension of supersymmetry).  A new PhD dissertation expands on the seminal work of Arnowitt, Deser and Misner regarding the global conservation properties of GR extrapolating them in a sensible way to localize the GR effects that they discussed globally. This thesis cites the following papers by these collaborators, four from 1959-1961 and one republished in 2008.

* Non-local modifications of GR to explain dark energy effects without a scalar field or f(R) theory.

* A memorial recalling Dirac's work on gravity.

* A no go result on quantum field theories of gravity.

Deser's papers address many fundamental questions in physics with a clarity of exposition that is lacking in many newer publication.

This is as good a place as any to note a Neo-Newtonian Gravity scheme that retains the easy of this theory vis-a-vis GR when GR modifications are modest, while fixing flaws in Newtonian gravity relative to GR that don't make Newtonian gravity much harder to work with mathematically.
