Noncommutativity and Physics: A non-technical review
Ali H. Chamseddine, Alain Connes, Walter D. van Suijlekom
We give an overview of the applications of noncommutative geometry to physics. Our focus is entirely on the conceptual ideas, rather than on the underlying technicalities. Starting…
Scalar Curvature in Discrete Gravity
Ali H. Chamseddine, Ola Malaeb, Sara Najem
We focus on studying, numerically, the scalar curvature tensor in a two-dimensional discrete space. The continuous metric of a two-sphere is transformed into that of a lattice usin…
The role of the 1.5 order formalism and the gauging of spacetime groups in the development of gravity and supergravity theories
Ali H. Chamseddine, Peter West
The 1.5 formalism played a key role in the discovery of supergravity and it has been used to prove the invariance of essentially all supergravity theories under local supersymmetry…
