Symmetry structure of special geometries [PDF]
, 1992 Using techniques from supergravity and dimensional reduction, we study the full isometry algebra of K\"ahler and quaternionic manifolds with special geometry.

Similar or Different? Configurations of Authenticity Across Museum Types
Curator: The Museum Journal, EarlyView.ABSTRACT Authenticity is traditionally regarded as playing a crucial role in museums, science centers, and memorials. However, despite this fact, authenticity has very different meanings in different (institutional) settings. This complicates shared communications across museum practices.

Cosmological Observations in a Modified Theory of Gravity (MOG)
Galaxies, 2013 Our Modified Gravity Theory (MOG) is a gravitational theory without exotic dark matter, based on an action principle. MOG has been used successfully tomodel astrophysical phenomena, such as galaxy rotation curves, galaxy cluster masses and lensing.

Perturbation Theory in Nonstandard Cosmology
Advances in Astrophysics, 2019 We explore a nonstandard model for the Universe in which we take a vacuum solution of Einstein’s equation as background and introduce visible matter and radiation as perturbations. The perturbation theory is greatly simplified by using the mapping on the inner Schwarzschild solution.

Aspects of compactifications and black holes in four-dimensional supergravity [PDF]
, 2010 In the 20th century, theoretical physics has seen the development of General Relativity and the Standard Model of elementary particles. These theories describe, with great precision, gravity and all known matter, respectively. However, it is not possible

Entropy and correlators in quantum field theory [PDF]
, 2010 It is well known that loss of information about a system, for some observer, leads to an increase in entropy as perceived by this observer. We use this to propose an alternative approach to decoherence in quantum field theory in which the machinery of ...

Marxism and Decolonizing Praxis: From Decolonial Misinterpretations to Marxist Contributions
Development and Change, EarlyView.ABSTRACT This article intervenes in postcolonial and decolonial critiques that portray Karl Marx and Marxism as intrinsically Eurocentric and inattentive to race, colonialism and non‐European revolutionary agency. It argues that such critiques often rely on selective, historically limited interpretations that overlook Marx's later writings, in which he

braneworld cosmology and holography [PDF]
, 2002 This thesis is devoted to studying two important aspects of braneworld physics: their cosmology and their holography. We examine the Einstein equations induced on a general (n - 2)-brane of arbitrary tension, embedded in some n-dimensional bulk.

The effective action of warped M-theory reductions with higher derivative terms — part I [PDF]
, 2015 M-theory accessed via eleven-dimensional supergravity admits globally consistent warped solutions with eight-dimensional compact spaces if background fluxes and higher derivative terms are considered.
