Product Einstein Manifolds, Zeta-Function Regularization and the Multiplicative Anomaly
Addition multiplication Laplace symmetric Spaces the product space
2014/12/22
The global additive and multiplicative properties of Laplace type operators acting on irreducible rank 1 symmetric spaces are considered. The explicit form of the zeta function on product spaces and o...
SU(3) baryon chiral perturbation theory and long distance regularization
Chiral perturbation theory the low energy goldstein boson
2014/12/22
The use of SU(3) chiral perturbation theory in the analysis of low energy meson-baryon interactions is discussed. It is emphasized that short distance effects, arising from propagation of Goldstone bo...
Long distance regularization in chiral perturbation theory with decuplet fields
Baryon chiral perturbation theory the octet axial vector coupling magnetic
2014/12/20
We investigate the use of long distance regularization in SU(3) baryon chiral perturbation theory with decuplet fields. The one-loop decuplet contributions to the octet baryon masses, axial-vector cou...
Regularization of Diagrammatic Series with Zero Convergence Radius
Expansion macroscopic system graphic technology system model diagram structure
2014/12/19
The divergence of perturbative expansions which occurs for the vast majority of macroscopic systems and follows from Dyson’s collapse argument prevents the direct use of Feynman’s diagrammatic techniq...
Notes on the Schwinger model: regularization and gauge invariance
the Schwinger model regularization and gauge invariance Mathematical Physics
2012/6/21
The point-splitting computation of the gauge invariant Hamiltonian for the Schwinger model on the circle in a positive energy representation is presented.
Geometrically relating momentum cut-off and dimensional regularization
β function Hopf Algebra momentum cut-off regularization dimensional regularization
2011/9/22
Abstract: The $\beta$ function for a scalar field theory describes the dependence of the coupling constant on the renormalization mass scale. This dependence is affected by the choice of regularizatio...
The effect of subfilter-scale physics on regularization models
subfilter-scale Lagrangian-averaged Navier-Stokes alpha-model magnetohydrodynamics
2010/4/6
The subfilter-scale (SFS) physics of regularization models are investigated to understand the regularizations' performance as SFS models. The strong suppression of spectrally local SFS interactions an...
Regularization parameters for the self-force of a scalar particle in a general orbit about a Schwarzschild black hole
scalar particle Schwarzschild black hole
2010/3/18
The interaction of a charged particle with its own field results in the "self-force" on the particle, which includes but is more general than the radiation reaction force. In the vicinity of the parti...
On the regularization of the constraints algebra of Quantum Gravity in 2+1 dimensions with non-vanishing cosmological constant
Quantum Gravity cosmological constant 2+1 dimensions
2010/3/18
We use the mathematical framework of loop quantum gravity (LQG) to study the quantization of three dimensional (Riemannian) gravity with positive cosmological constant (Lambda>0). We show that the usu...
