    Tolman - Bayin type static charged fluid spheres in general relativity
    (2011-07-05) Ray, Saibal; Das, Basanti
    In a static spherically symmetric Einstein-Maxwell spacetime the class of astrophysical solu- tion found out by Ray and Das (2002) and Pant and Sah (1979) are revisited here in connection to the phenomenological relationship between the gravitational and electromagnetic fields. It is qualitatively shown that the charged relativistic stars of Tolman (1939) and Bayin (1978) type are of purely electromagnetic origin. The existence of this type of astrophysical solutions is a probable extension of Lorentz’s conjecture that electron-like extended charged particle possesses only ‘electromagnetic mass’ and no ‘material mass’.

    Operational indistinguishabilty of doubly special relativities from special relativity
    (2011-07-05) Ahluwalia, D.V.
    We argue that existing doubly special relativities may not be operationally distinguishable from the special relativity. In the process we point out that some of the phenomenologically motivated modifications of dispersion relations, and arrived conclusions, must be reconsidered. Finally, we reflect on the possible conceptual issues that arise in quest for a theory of spacetime with two invariant scales.
