    On hypersurfaces in a locally affine Riemannian Banach manifold II by El-Said R. Lashin, Tarek F. Mersal

    Published 2004-01-01
    “…In our previous work (2002), we proved that an essential second-order hypersurface in an infinite-dimensional locally affine Riemannian Banach manifold is a Riemannian manifold of constant nonzero curvature. In this note, we prove the converse, in other words, we prove that a hypersurface of constant nonzero Riemannian curvature in a locally affine (flat) semi-Riemannian Banach space is an essential hypersurface of second order.…”

    Geometric Description of the Thermodynamics of the Noncommutative Schwarzschild Black Hole by Alexis Larrañaga, Natalia Herrera, Juliana Garcia

    Published 2013-01-01
    “…Using a thermodynamic metric which is invariant with respect to Legendre transformations, we determine the geometry of the space of equilibrium states and show that phase transitions, which correspond to divergencies of the heat capacity, are represented geometrically as singularities of the curvature scalar. This further indicates that the curvature of the thermodynamic metric is a measure of thermodynamic interaction.…”

    The Global Symmetry Group of Quantum Spectral Beams and Geometric Phase Factors by Elias Zafiris

    Published 2015-01-01
    “…In the course of this schema, we introduce the notion of Hermitian differential line sheaves or unitary rays and classify their gauge equivalence classes in terms of a global differential invariant given by the de Rham cohomology class of the curvature. Furthermore, we formulate and interpret physically the curvature recognition integrality theorem for unitary rays. …”
