    In this work we present an analysis of the one-loop Slavnov-Taylor identities in noncommutative QED4_4. The vectorial fermion-photon and the triple photon vertex functions were studied, with the conclusion that no anomalies arise.Comment: 24 pages, revtex4, v2: typos correcte

    Gravitational Collapse of Self-Similar and Shear-free Fluid with Heat Flow

    Full text link
    A class of solutions to Einstein field equations is studied, which represents gravitational collapse of thick spherical shells made of self-similar and shear-free fluid with heat flow. It is shown that such shells satisfy all the energy conditions, and the corresponding collapse always forms naked singularities.Comment: 34 pages, 9 figures, late
