Applications of cosmological perturbation theory [PDF]

open access: yes, 2011
PhDCosmological perturbation theory is crucial for our understanding of the universe. The linear theory has been well understood for some time, however developing and applying the theory beyond linear order is currently at the forefront of research in

Little rip, pseudo rip and bounce cosmology with generalized equation of state in non-standard backgrounds

open access: yesEuropean Physical Journal C: Particles and Fields
The discovery of universe’s late-time acceleration and dark energy has overseen a great deal of research into cosmological singularities and particularly future singularities.

The Relevance of Irrelevance: Absolute Objects and the Jones-Geroch Dust Velocity Counterexample, with a Note on Spinors [PDF]

open access: yes, 2005
James L. Anderson analyzed the conceptual novelty of Einstein's theory of gravity as its lack of ``absolute objects.'' Michael Friedman's related concept of absolute objects has been criticized by Roger Jones and Robert Geroch for implausibly admitting ...

Nonlinear perturbations in Relativistic cosmology

open access: yes, 2015
학위논문(박사)--서울대학교 대학원 :자연과학대학 물리·천문학부,2015. 2. 이수종.In this dissertation, we discuss the inhomogeneity growth in the universe. The inhomogeneity growth is originated from the gravitational instability and we consider the Newtonian and the Einstein gravity ...

Analogy between dislocation creep and relativistic cosmology

open access: yes, 2017
Se presenta una analogía formal y física entre la deformación plástica, principalmente termofluencia por dislocaciones y cosmología relativista. Se muestran la analogía física entre ocho expresiones de termofluencia por dislocaciones y cosmología ...
