(3+1)-Formulation for Gravity with Torsion and Non-Metricity II: The Hypermomentum Equation
Seramika Ariwahjoedi, Agus Suroso, F. P. Zen
In this article, we consider a special case of Metric-Affine f(R)-gravity for f(R) = R, i.e. the Metric-Affine General Relativity (MAGR). As a companion to the first article in the…
(3+1)-Formulation for Gravity with Torsion and Non-Metricity: The Stress-Energy-Momentum Equation
Seramika Ariwahjoedi, Agus Suroso, F. P. Zen
We derive the generalized Gauss-Codazzi-Mainardi (GCM) equation for a general affine connection with torsion and non-metricity. Moreover, we show that the metric compatibility and…
Hermiticity of the Volume Operators in Loop Quantum Gravity
S. Ariwahjoedi, I. Husin, I. Sebastian +1
The aim of this article is to provide a rigorous-but-simple steps to prove the hermiticity of the volume operator of Rovelli-Smolin and Ashtekar-Lewandowski using the angular momen…
Contracted Bianchi Identity and Angle Relation on n-dimensional Simplicial Complex of Regge Calculus
Seramika Ariwahjoedi, Freddy P. Zen
In this article, we prove the theorems concerning the trace relation of SO(3), SU(2), and SO(n) which are representation of SO(3) and SU(2). An interesting fact we found is the tra…
(2+1) Regge Calculus: Discrete Curvatures, Bianchi Identity, and Gauss-Codazzi Equation
Seramika Ariwahjoedi, Freddy P. Zen
The first results presented in our article are the clear definitions of both intrinsic and extrinsic discrete curvatures in terms of holonomy and plane-angle representation, a clea…
