Inflation: Limits of Slowdawn

Relic gravitational waves and limits on inflation.

It is shown that only a narrow class of inflationary models can possibly agree with the available observational data on the anisotropy of the cosmic microwave background radiation (CMBR). These models may be governed by “matter” with the effective equation of state −1.2 < p/ǫ < −0.6 which includes the De-Sitter case p/ǫ = −1. PACS numbers: 98.80.Cq, 98.70.Vc, 04.30.+ Typeset using REVTEX 1 The ...

Fiscal limits and monetary policy: default vs. inflation

a r t i c l e i n f o This paper studies the monetary policy trade-off between low inflation and low sovereign risk in the environment where fiscal authorities fail to fully ensure the sustainability of government debt. Building on the Fiscal Theory of Price Level (FTPL) and the Fiscal Theory of Sovereign Risk (FTSR), this paper differs in its baseline assumption about the monetary policy objec...

Black hole relics and inflation: Limits on blue perturbation spectra.

Blue primordial power spectra have spectral index n > 1 and arise naturally in the recently proposed hybrid inflationary scenario. An observational upper limit on n is derived by normalizing the spectrum at the quadrupole scale and considering the possible overproduction of Planck mass relics formed in the final stage of primordial black hole evaporation. In the inflationary Universe with the m...

Limits in modified categories of interest

‎We firstly prove the completeness of the category of crossed modules in a modified category of interest‎. ‎Afterwards‎, ‎we define pullback crossed modules and pullback cat objects that are both obtained by pullback diagrams with extra structures on certain arrows‎. ‎These constructions unify many corresponding results for the cases of groups‎, ‎commutative algebras and can also be adapted to ...
